Let’s go through each object one by one and think about what makes sense for its capacity.

---

1. Baby bottle
A baby bottle holds milk or formula — not a lot, but enough for a feeding.
250 liters? That’s like a big bathtub! Too much.
250 ml? Yes — that’s about 1 cup. Perfect for a baby bottle.
✔ Tick: 250 ml

---

2. Ketchup bottle
Ketchup bottles are small — you squeeze them on fries or burgers.
300 liters? No way — that’s huge!
300 ml? Yes — that’s about the size of a small juice box. Makes sense.
✔ Tick: 300 ml

---

3. Water bottle (plastic)
This looks like a standard single-serving water bottle.
1 ml? That’s just a few drops — too tiny!
1 L? Yes — most plastic water bottles hold 500 ml to 1 liter. This is reasonable.
✔ Tick: 1 L

4. Watering can
You use this to water plants — it needs to hold a fair amount of water.
3 ml? That’s less than a teaspoon — useless for watering!
3 L? Yes — that’s about 3 big soda bottles worth. Good for gardening.
✔ Tick: 3 L

---

5. Soda can
A regular soda can is small — you drink it in one sitting.
150 liters? Way too big — that’s like a mini pool!
150 ml? Hmm… actually, most soda cans are 330 ml or 355 ml. But between 150 ml and 150 L, 150 ml is closer — even if a bit small, it’s still better than 150 L. Wait — let me double-check. Actually, some small cans (like energy drinks) are around 150–250 ml. So yes, 150 ml is the better estimate here compared to 150 L.
✔ Tick: 150 ml

*(Note: In real life, a standard soda can is ~330 ml, but since 150 L is absurdly large, 150 ml is the only logical choice given the options.)*

6. Coffee mug
You drink coffee or tea from this — not too much at once.
100 liters? Impossible — that’s more than a bathtub!
100 ml? A bit small — most mugs are 200–300 ml. But again, between 100 ml and 100 L, 100 ml is the only sensible option. Maybe it’s a small espresso cup? Still, 100 ml is acceptable as an estimate vs. 100 L.
✔ Tick: 100 ml

*(Again, realistically, a mug is often 250 ml, but since 100 L is ridiculous, we pick 100 ml as the “better” estimate among the two choices.)*

Final Answer:

- Baby bottle → 250 ml
- Ketchup bottle → 300 ml
- Water bottle → 1 L
- Watering can → 3 L
- Soda can → 150 ml
- Coffee mug → 100 ml
