The correct answer is A. Vitamin A.

Vitamin A is essential for good vision, especially in dim light. It is needed to produce a pigment in the retina called rhodopsin, which is necessary for vision in low-light conditions. A lack of vitamin A can lead to night blindness, which is the inability to see in dim light.

Vitamin B is a group of vitamins that are essential for many bodily functions, including energy production, cell function, and nerve function. Vitamin B deficiency can cause a variety of symptoms, including fatigue, weakness, and nerve problems. However, vitamin B deficiency does not typically cause night blindness.

Vitamin C is a water-soluble vitamin that is essential for the growth and repair of tissues, the production of collagen, and the absorption of iron. Vitamin C deficiency can cause a variety of symptoms, including fatigue, weakness, and bleeding gums. However, vitamin C deficiency does not typically cause night blindness.

Vitamin D is a fat-soluble vitamin that is essential for the absorption of calcium and phosphorus. Vitamin D deficiency can cause a variety of symptoms, including bone pain, muscle weakness, and fatigue. However, vitamin D deficiency does not typically cause night blindness.
