Let’s solve this step by step.

The worksheet is about choosing between the letters C and K to complete words. The goal is to figure out which letter makes a real word when placed in the blank.

We’ll go row by row, column by column, and fill in the blanks with either C or K to make real words.

---

First Column:

1. _ut → Cut (C) — “Kut” is not a word.
2. _iss → Kiss (K) — “Ciss” is not a word.
3. _at → Cat (C) — “Kat” is sometimes used as a name, but “cat” is the standard word.
4. _uff → Cuff (C) — “Kuff” is not a word.
5. _it → Kit (K) — “Cit” is not a common word; “kit” is correct.

So first column: C, K, C, C, K

---

Second Column:

1. _ept → Kept (K) — “Cept” is not a word (though “except” exists, it’s not just “cept”).
2. _id → Kid (K) — “Cid” is not a standard English word.
3. _ot → Got? Wait — no, we’re only using C or K. So Cot (C) — “Got” uses G, so not allowed. “Cot” is a real word.
4. _od → Cod (C) — “Kod” is not a word.
5. _od → Wait, same as above? Actually, looking again — maybe it’s “God”? But again, only C or K. So Cod (C) — already used? Or perhaps it’s a typo? Let’s assume it’s meant to be “Cod” again or maybe “Kod” isn’t valid. Actually, looking at the image — the last one in middle column is “_od”, and above it is “_ot”. So:

Wait — let me recheck the image description from user:

Middle column words:
- _ept
- _id
- _ot
- _od
- (bottom one cut off? User says “_od” then “t” at bottom right — probably not part of middle column)

Actually, from the image description given in the prompt:

Middle column:
_ ept
_ id
_ ot
_ od
(and maybe one more? But user didn’t specify)

Assuming 5 rows total per column.

So:

_ ept → Kept (K)
_ id → Kid (K)
_ ot → Cot (C)
_ od → Cod (C)
Last one? Maybe “_et”? But not listed. Let’s stick to what’s visible.

In the image, there’s a popsicle stick with “k” covering part of the middle column — specifically over “_id” and “_ot” area. That suggests the student is testing “k” for those.

But we must choose correctly.

So second column: K, K, C, C, ?

If fifth is “_et” → “Ket” is slang, not standard. “Cet” not a word. Maybe it’s “_it” again? Not clear. Let’s skip and do third column.

---

Third Column:

1. _ub → Cub (C) — “Kub” not a word.
2. _im → Kim (K) — proper noun, but acceptable. “Cim” not a word.
3. _ab → Cab (C) — “Kab” not standard.
4. _en → Ken (K) — proper noun, but also means knowledge. “Cen” not a word.
5. _t → Cat (C)? But that’s 3 letters. “_t” could be “at”, “it”, etc. — but we need C or K. “Ct” not a word. “Kt” not a word. Hmm.

Wait — looking back at user’s image description:

Third column:
_ ub
_ im
_ ab
_ en
_t ← this might be “_at” or “_it”? But written as “_t”

Actually, in the original image (as described), the last row of third column is “_t” — which is incomplete. Probably a typo or cut off.

But let’s assume it’s “_at” → “Cat” (C) or “Kat” (K). “Kat” is informal for cat, but “cat” is standard.

Alternatively, maybe it’s “_et” → “Ket” not standard.

Given that, let’s list all possible correct answers based on standard English words:

---

Finalizing each:

Column 1:
- _ut → Cut
- _iss → Kiss
- _at → Cat
- _uff → Cuff
- _it → Kit

Column 2:
- _ept → Kept
- _id → Kid
- _ot → Cot
- _od → Cod
- (fifth? If “_et” → no good word with C/K. Maybe “_at” again? But let’s say if it’s “_it” → Kit (K). But not specified. Since user didn’t specify fifth, and image may have cut off, we’ll assume 4 per column or accept as is.)

Actually, counting the rows in user’s description:

Left column: _ut, _iss, _at, _uff, _it → 5 words
Middle: _ept, _id, _ot, _od → only 4? But image shows 5 rows. Last one might be “_et” or something. To avoid confusion, let’s focus on the ones clearly visible.

From the image description provided by user, the middle column has:

_ ept
_ id
_ ot
_ od
and then below that, partially visible, but not named.

Similarly, right column:

_ ub
_ im
_ ab
_ en
_t ← likely “_at” or “_it”

To resolve, let’s use common words:

For “_t” — if it’s “_at”, then Cat (but already used in col1). Or Kat — acceptable as variant.

But better to pick most standard.

Perhaps “_t” is “_it” → Kit (again, but ok).

Since the task is to choose C or K for each, and many words are unique, let’s compile:

---

Final Answers per position:

Left Column:
1. _ut → C
2. _iss → K
3. _at → C
4. _uff → C
5. _it → K

Middle Column:
1. _ept → K
2. _id → K
3. _ot → C
4. _od → C
5. (assume _et or _it — if _it → K, but let’s say if it’s “_at” → C. However, since not specified, and to match pattern, perhaps it’s “_et” — no good. Maybe it’s “_ot” again? Unlikely. Let’s skip and note.)

Actually, looking at the image description again — the user wrote:

“_ept
_ id
_ ot
_ od
” — and then in the next line, for right column “_ub” etc.

And at the bottom, right column has “_t” — which is likely the fifth row.

So for middle column fifth row — not specified. Perhaps it’s missing. We’ll assume 4 for middle, 5 for others.

But to be consistent, let’s count 5 rows.

Another idea: in the middle column, after “_od”, it might be “_et” — but “ket” is not standard. “Cet” not a word. So perhaps it’s “_it” → Kit.

I think it’s safe to assume:

Middle column fifth: _it → Kit (same as left column fifth, but that’s ok — repetition happens).

Similarly, right column fifth: _t → if “_at” → Cat, but already used. Or “_it” → Kit.

But “_t” alone is ambiguous.

Looking at the actual image (from memory or standard such worksheets), often the last one is “_at” or “_et”.

To resolve, let’s use:

Right column:
1. _ub → Cub
2. _im → Kim
3. _ab → Cab
4. _en → Ken
5. _t → Cat (assuming “_at”)

But “_t” written as is — perhaps it’s “_it” → Kit.

I think the safest is to go with common words and avoid duplicates if possible, but duplicates are allowed.

Final decision:

Right Column:
1. _ub → C
2. _im → K
3. _ab → C
4. _en → K
5. _t → C (for “Cat”) — assuming it’s “_at”

But to match the format, let’s list all.

Since the task is to provide the final answer, and the user didn’t specify how to present, but from context, likely they want the letters filled in.

But the instruction says: “Provide only the final correct answer”

And since it’s a worksheet, perhaps list the choices.

But to be precise, let’s create a grid.

However, the simplest way is to state the correct letter for each blank in order.

But there are 15 blanks (5 columns x 3 columns? No, 3 columns, 5 rows each = 15 words).

List them row by row, left to right.

Row 1: _ut, _ept, _ub → C, K, C
Row 2: _iss, _id, _im → K, K, K
Row 3: _at, _ot, _ab → C, C, C
Row 4: _uff, _od, _en → C, C, K
Row 5: _it, _it (assume), _at (assume) → K, K, C

But for row 5 middle, if it’s “_it”, then K; if “_ot”, already used.

To avoid overcomplicating, and since the popsicle stick has “k” and is covering “_id” and “_ot” area, but “_ot” should be “Cot”, so the student might be mistaken.

But our job is to give correct answers.

Final correct choices:

For each word:

- cut: C
- kept: K
- cub: C
- kiss: K
- kid: K
- kim: K
- cat: C
- cot: C
- cab: C
- cuff: C
- cod: C
- ken: K
- kit: K
- (fifth middle: if _it: K)
- (fifth right: if _at: C)

So compiling in order of appearance (left to right, top to bottom):

1. C (cut)
2. K (kept)
3. C (cub)
4. K (kiss)
5. K (kid)
6. K (kim)
7. C (cat)
8. C (cot)
9. C (cab)
10. C (cuff)
11. C (cod)
12. K (ken)
13. K (kit)
14. K (for middle fifth, assume kit)
15. C (for right fifth, assume cat)

But this has duplicates, which is fine.

Since the worksheet likely expects one letter per blank, and the student is to cut out C and K and glue, but for solving, we provide the correct letter for each.

But the final answer should be the completed words or the letters.

Given the format, perhaps list the letters in a sequence.

But to match the instruction, "provide only the final correct answer", and since it's a worksheet, maybe state the choices.

I think the best is to provide the correct letter for each blank in the order they appear.

So:

First row: C, K, C
Second row: K, K, K
Third row: C, C, C
Fourth row: C, C, K
Fifth row: K, K, C [assuming middle fifth is "kit" and right fifth is "cat"]

But for fifth row middle, if it's "_ot" again, but that would be duplicate, so likely "_it" or "_et".

Upon second thought, in many such worksheets, the words are unique, so let's check if all can be unique.

Possible words:

Left: cut, kiss, cat, cuff, kit
Middle: kept, kid, cot, cod, ? — "ket" not good, "cet" not, so perhaps "kit" again, or "cot" is repeated? Unlikely.

Another idea: middle fifth might be "_et" -> "get" but not C/K. Or "bet". No.

Perhaps it's "_at" -> "cat", but already in left.

I think it's acceptable to have repeats.

So final answer as a grid:

C K C
K K K
C C C
C C K
K K C

But to write it clearly.

Since the user might expect the letters for each position, and the final answer should be concise.

Perhaps list the correct letter for each word in order.

But to save space, I'll provide the sequence.

Final Answer:
C, K, C, K, K, K, C, C, C, C, C, K, K, K, C

But let's verify the count: 5 rows x 3 columns = 15 items.

Positions:

1. _ut: C
2. _ept: K
3. _ub: C
4. _iss: K
5. _id: K
6. _im: K
7. _at: C
8. _ot: C
9. _ab: C
10. _uff: C
11. _od: C
12. _en: K
13. _it: K
14. (middle fifth): K [assuming _it]
15. (right fifth): C [assuming _at]

Yes.

So the final answer is the sequence of correct letters.

But to present it nicely.

Since the task is to solve, and the answer is the filled-in letters, I'll box the sequence.

Final Answer:
C, K, C, K, K, K, C, C, C, C, C, K, K, K, C

But let's double-check "kim" — is it acceptable? Yes, as a proper noun, and in phonics, it's often used.

Similarly, "ken" is acceptable.

"cot" and "cod" are clear.

"kit" is clear.

So I think this is correct.
