Which of the following is the richest source of Vitamin C?

Correct answer: (d) Amla

Explanation

Amla (Indian gooseberry) is the richest natural source of Vitamin C among the options.

Vitamin C (ascorbic acid) is water-soluble; its deficiency causes scurvy.

Orange has only about 53 mg per 100 g, far below amla; carrot is rich in Vitamin A, not C.
