Which pair of vitamins are antioxidants according to the material?

• A. A and D
• B. C and D
• C. C and E
• D. B and C

Answer: (C)

Antioxidants protect cells by neutralizing free radicals, preventing oxidative damage. Vitamin C is a water-soluble antioxidant that donates electrons to reactive species in body fluids, helping to protect proteins, DNA, and other molecules. Vitamin E is a fat-soluble antioxidant that sits in cell membranes and interrupts lipid peroxidation, safeguarding membrane integrity. They can also work together, with vitamin C helping to regenerate vitamin E after it has neutralized a radical, strengthening the overall antioxidant defense. In the material, these two vitamins are identified as antioxidants, which is why they form the correct pairing. The other vitamins listed are not described as antioxidants in that context, so they don’t fit as the paired answer.
