Correct Answer: C

Rationale: Vitamin C is well-known for its antioxidant properties, helping to protect cells from damage caused by free radicals. This essential vitamin plays a crucial role in immune function and collagen synthesis.

Option A, Vitamin D, primarily supports bone health and immune function but does not exhibit antioxidant activity. Option B, Pyridoxine (Vitamin B6), is vital for metabolism and brain health, yet lacks antioxidant properties. Option D, Niacin (Vitamin B3), is important for energy production and skin health, but it does not function as an antioxidant. Thus, Vitamin C stands out as the key antioxidant among the options.
