Answer: (B)

Verified step by step guidance

1. Understand the role of Vitamin C in the body. Vitamin C, also known as ascorbic acid, is a water-soluble vitamin that plays several important roles in human health.
2. Recognize that Vitamin C is crucial for collagen synthesis. Collagen is a protein that provides structure to skin, bones, and connective tissues. Vitamin C acts as a cofactor for enzymes involved in the hydroxylation of proline and lysine, which are essential steps in collagen formation.
3. Differentiate the functions of Vitamin C from other vitamins. For example, Vitamin A is associated with vision improvement, Vitamin K is involved in blood clotting, and Vitamin D aids in calcium absorption.
4. Identify that Vitamin C does not directly improve vision, aid in blood clotting, or enhance calcium absorption. These functions are associated with other vitamins and nutrients.
5. Conclude that the primary function of Vitamin C relevant to the options provided is collagen synthesis, which is essential for maintaining healthy skin, blood vessels, and bones.
