Option 1: Both the assertion (A) and the reason (R) are individually true, and R is the correct explanation of A.

Option 2: Both the assertion (A) and the reason (R) are individually true, but R is not the correct explanation of A.

Option 3: The assertion (A) is true, but the reason (R) is false.

Option 4: The assertion (A) is false, but the reason (R) is true.

The correct answer is option 3: A is true, but R is false.

Explanation:

Citric acid is indeed used in soft drinks, which supports the assertion (A). It is commonly used as a flavoring and preservative agent in various carbonated and non-carbonated beverages, including soft drinks.

However, the reason provided (R) states that citric acid is a good substitution for acetic acid in soft drinks, which is incorrect. Acetic acid is not commonly used in soft drinks, and citric acid is not typically used as a substitute for acetic acid in this context. Therefore, the reason (R) does not correctly explain why citric acid is used in soft drinks.

Hence, option 3 is the correct answer.
