Answer 1

Answer:

C. A cofactor of collagen synthesis

Explanation:

Vitamin C is a water-soluble vitamin, antioxidant, and essential co-factor for collagen biosynthesis, carnitine and catecholamine metabolism, and dietary iron absorption. Humans are unable to synthesize vitamin C, so it is strictly obtained through dietary intake of fruits and vegetables.
