Which vitamin is NOT listed as an antioxidant in the material?

Explanation:
Antioxidants protect cells from damage by neutralizing free radicals. In typical nutrition material, the vitamins listed as antioxidants are Vitamin A, ascorbic acid (Vitamin C), and tocopherol (Vitamin E). Vitamin A helps quench reactive species, ascorbic acid donates electrons to neutralize oxidants and also helps recycle other antioxidants, and tocopherol protects cell membranes from lipid damage. Vitamin D is mainly involved in calcium and phosphorus metabolism and bone health, with immune and other roles, and it is not described as an antioxidant in standard materials. So Vitamin D is the one not listed as an antioxidant.
