Correct:
B
Explanation
Vitamin C is chemically known as ascorbic acid [2]. It is a naturally occurring carboxylic acid found in various food sources, particularly citrus fruits like oranges and lemons, as well as amla [3]. Ascorbic acid serves as a vital nutrient and antioxidant in the human body [4]. In contrast, the other options represent different organic acids: methanoic acid (also known as formic acid) is found in ant and nettle stings [2]; lactic acid is found in sour milk or curd [2]; and tartaric acid is present in tamarind, grapes, and unripe mangoes [3]. Ascorbic acid is unique among these for its specific role as a vitamin, whereas the others are primarily metabolic byproducts or defensive chemicals in nature [3].
