Correct:
A
Explanation
The question asks to identify the pairs that are NOT correctly matched:
- Lactic acid: It is produced during the fermentation of lactose in milk by bacteria, making it a primary component of curd and yogurt. (Correctly matched)
- Tartaric acid: This organic acid occurs naturally in many plants, particularly in grapes, tamarind, and bananas. (Correctly matched)
- Acetic acid: It is the main constituent of vinegar. Potatoes do not naturally contain acetic acid; they primarily contain citric and malic acids. (Incorrectly matched)
Since only the third pair is incorrect, the correct option is A.
