Solution

Xerophthalmia is a medical condition in which the eye fails to produce tears. It is characterized by abnormal dryness of the conjunctiva and cornea of the eye. This condition is primarily caused by a severe deficiency of Vitamin A (retinol). Vitamin A is essential for the maintenance of healthy epithelial tissues and the production of visual pigments in the retina. Prolonged deficiency leads to night blindness, followed by xerophthalmia, and can eventually result in permanent blindness if left untreated.

Answer: Vitamin-A

Hence, the correct answer is option: 'A'.
