Let’s go step by step to match each question in Column A with the correct answer in Column B.

We’ll read each description and think about which body system or part it matches.

---

1. This provides structure to the human body and protects vital organs.
→ That’s the skeletal system — bones give us shape and protect things like the brain, heart, and lungs.
✔ Match: K. Skeletal system

---

2. It is also known as the circulatory system and carries nutrients throughout the body.
→ The circulatory system = cardiovascular system (heart + blood vessels).
✔ Match: F. Cardiovascular system

---

3. It is known as the body’s control center.
→ That’s the brain — it controls everything we do, think, and feel.
✔ Match: I. Brain

*(Note: Some might say “nervous system,” but here “Brain” is listed separately and fits best for “control center.”)*

---

4. This system includes the body’s largest organ, the skin.
→ Skin is part of the integumentary system (skin, hair, nails).
✔ Match: E. Integumentary system

---

5. It is the system that supports the body’s movement.
→ Muscles pull on bones to make us move → Muscular System
✔ Match: G. Muscular System

---

6. This system helps the body in removing excess water, toxins, and other cellular wastes.
→ That’s the job of the excretory system (kidneys, bladder, etc.).
✔ Match: D. Excretory system

---

7. It transmits electrical impulses throughout the body.
→ Nerves send electric signals → this is the central nervous system (brain + spinal cord) or just nervous system. But since “Central nervous system” is an option, and it handles transmission…
Wait — actually, the *entire* nervous system does this, but “Central nervous system” is more specific to brain/spinal cord. However, looking at options, J. Central nervous system is the closest fit.
But let’s double-check: Question 3 was “control center” → Brain (I), so question 7 is likely referring to the system that sends messages → still CNS or maybe peripheral? Hmm.

Actually, re-reading: “transmits electrical impulses throughout the body” — that’s nerves everywhere → but among choices, J. Central nervous system is the only one related to nerve signaling. Alternatively, could it be “nervous system”? Not listed. So yes, J is best.

✔ Match: J. Central nervous system

*(Note: In some curricula, they may simplify and call the whole thing “nervous system,” but since “Central nervous system” is given, and it’s responsible for processing and transmitting signals, we’ll go with J.)*

---

8. It is the system that works in the fertilisation and propagation of genes.
→ That’s reproduction → making babies, passing on genes → Reproductive system
✔ Match: C. Reproductive system

---

Now let’s list all our matches:

1 → K
2 → F
3 → I
4 → E
5 → G
6 → D
7 → J
8 → C

Wait — what about the others? We have 12 options (A–L), but only 8 questions shown. That’s okay — not all will be used.

Also, note: Question 9 is cut off (“This system helps provide energy to the...”) — probably digestive or respiratory, but since it’s incomplete, we ignore it.

So final matching:

1. K
2. F
3. I
4. E
5. G
6. D
7. J
8. C

Let me verify once more:

- Structure & protection → skeletal → K ✔️
- Circulatory/nutrients → cardiovascular → F ✔️
- Control center → brain → I ✔️
- Largest organ (skin) → integumentary → E ✔️
- Movement → muscular → G ✔️
- Remove waste → excretory → D ✔️
- Electrical impulses → central nervous system → J ✔️
- Fertilization/genes → reproductive → C ✔️

All make sense!

Final Answer:
1-K, 2-F, 3-I, 4-E, 5-G, 6-D, 7-J, 8-C
