Answer 1

The Correct Option is A

Step 1: Role of Vitamin A in Vision.
Vitamin A is a fat-soluble vitamin that plays a crucial role in maintaining healthy vision. It is essential for the production of rhodopsin, a protein in the eyes that helps to see in low-light conditions. This makes Vitamin A vital for preventing night blindness.
Step 2: Sources of Vitamin A.
Vitamin A is found in foods like carrots, sweet potatoes, spinach, and liver. It is available in two forms: retinol (from animal sources) and provitamin A carotenoids (from plant sources), which the body can convert into retinol.
Step 3: Conclusion.
The correct answer is Vitamin A because it directly contributes to the health of the eyes, while other vitamins like Vitamin C and D have different functions related to immunity and bone health.
