Which vitamin is listed as an antioxidant in the material?

• A. Vitamin A
• B. Vitamin D
• C. Ascorbic Acid
• D. Tocopherol

Answer: (A)

Antioxidants protect cells by neutralizing free radicals, preventing oxidative damage. Among vitamins, the strongest antioxidant roles are clearly seen with Vitamin E (tocopherol), which protects lipid membranes, and with Vitamin C (ascorbic acid), which scavenges reactive species and helps regenerate Vitamin E. The Vitamin A group, including carotenoids that are precursors to Vitamin A, can contribute to antioxidant defenses, but the retinol form itself is not typically classified as a primary antioxidant. If a material lists Vitamin A as an antioxidant, it’s likely referring to the antioxidant activity of related carotenoids rather than retinol itself. Vitamin D does not have a meaningful antioxidant role.
