Which vitamin is linked with the prevention of night blindness?

• A. Vitamin K
• B. Vitamin C
• C. Vitamin A
• D. Vitamin D

Answer: (C)

Vitamin A is crucial for maintaining good vision, particularly in low-light conditions. It plays a significant role in the formation of rhodopsin, a pigment found in the retina that is essential for seeing in dim light. When there is a deficiency of Vitamin A, the production of rhodopsin can be adversely affected, leading to night blindness, a condition characterized by difficulty seeing in low light or darkness. In terms of the other options, Vitamin K is more associated with blood clotting, Vitamin C is known for its antioxidant properties and role in collagen synthesis, and Vitamin D is important for calcium absorption and bone health. None of these vitamins have a direct connection to night vision, which reinforces why Vitamin A is the correct choice in this context.
