Here is a brief explanation of each option:
- Option A: a-2, b-3, c-1, d-4. This option is correct because acetone is used in nail polish remover, carbon tetrachloride is used in fire extinguishers, iodoform is used in dressing wounds, and esters are found in fruit essence.
- Option B: a-3, b-1, c-2, d-4. This option is incorrect because acetone is not used in dressing wounds.
- Option C: a-1, b-4, c-2, d-3. This option is incorrect because carbon tetrachloride is not used in fruit essence.
- Option D: a-4, b-2, c-3, d-1. This option is incorrect because esters are not used in fire extinguishers.
