D Correct answer
Explanation

Vitamin C (ascorbic acid) is a water-soluble vitamin that is not stored in the body. Excess amounts are excreted through urine in higher vertebrates. Unlike fat-soluble vitamins (A, D, E, K) which can be stored in liver and adipose tissue, Vitamin C requires regular dietary intake as surplus is eliminated renally.
