Solution

The correct option is C Xerophthalmia
Xerophthalmia is caused by a severe vitamin A deficiency. It is described as dryness of the conjunctiva and cornea. The conjunctiva becomes dry, thick and wrinkled. If untreated, it can lead to corneal ulceration and ultimately to blindness as a result of corneal damage.
