A Correct answer
Explanation

Vitamin A deficiency is a leading cause of preventable blindness in children, particularly night blindness (nyctalopia). Vitamin A is essential for the formation of rhodopsin, the pigment in rod cells that enables vision in low-light conditions. Deficiency also causes dry eyes (xerophthalmia) and can lead to complete blindness if untreated.
