Deficiency of which of the following causes color blindness and poor vision?

Correct option is A

The correct answer is: (a) Vitamin A

Explanation:

Vitamin A is essential for maintaining good vision. A deficiency in Vitamin A can cause night blindness (poor vision in low light) and, in severe cases, lead to complete blindness.

Vitamin A is crucial for the production of a pigment called rhodopsin, which is necessary for vision in dim light.

It also plays a role in maintaining the health of the retina, which is crucial for vision.

other disease due to deficiency of vitamin A: Xerophthalmia

Information Booster:

1. Vitamin C: While Vitamin C is important for overall health, including boosting immunity and promoting healthy skin, it is not directly responsible for vision. Deficiency in Vitamin C leads to scurvy, which causes symptoms like gum disease and skin problems.

2. Calcium: Calcium is primarily important for bone health, muscle function, and nerve signaling. A deficiency in calcium can lead to bone diseases like osteoporosis.

3. Vitamin K: Vitamin K is mainly involved in blood clotting and bone health. A deficiency in Vitamin K leads to problems with blood clotting and may cause excessive bleeding.

Therefore, Vitamin A deficiency is the one most closely linked to color blindness and poor vision.
