What is one of the functions of the antioxidant vitamin A?

• A. Aids in the functioning and repair of the skin cells
• B. Maintains bone calcium
• C. Regulates blood pressure
• D. Absorbs iron efficiently

Answer: (A)

Vitamin A helps keep skin healthy by supporting the growth and differentiation of skin and other epithelial cells, which is essential for proper functioning and repair after injury. This means it plays a key role in wound healing and maintaining a strong skin barrier. The other options don’t match vitamin A’s main actions: bone calcium is governed mainly by vitamin D and minerals, blood pressure is regulated by fluids and hormones, and iron absorption is more strongly influenced by vitamin C and other factors.
