a. night blindness
b. colour blindness

Answer 1

Deficiency of Vitamin A causes night blindness, which is an eye disease due to which the patient cannot see things clearly at night or in the dim light.

So the option ‘a’ is the correct answer here.

Night blindness is counted among the most common Vitamin A deficiency symptoms that can be prevented by consuming the foods rich in Vitamin A.

Thus, the sufficient intake can prevent the degeneration of the sensory cells of the eye retina, which is the reason of night blindness.
