Hint: We know that Vitamins are essential for our body. Vitamins can be water soluble and fat soluble. The fat-soluble vitamins are Vitamin A, D, K and E. The water-soluble vitamins are Vitamin C and Vitamin Bs. Certain diseases are caused due to the low intake or low intake of certain vitamins and minerals.

Complete step by step answer:
Xerophthalmia is a condition in which our eyes fail to produce tears. It is an eye disease caused by vitamin A deficiency. It can also lead to night blindness and lead to damage to the cornea. The low intake of vitamin A-rich foods is one of the reasons.

Degeneration of lacrimal glands is also due to the deficiency of vitamin A. It leads to lesser production of tears and loss of response. The lacrimal gland is located within the orbit above the lateral end of the eye. It is one of the glands which is responsible for making tears. Due to deficiency of vitamin A, it is unable to produce tears and leads to degeneration of lacrimal glands.

Night blindness is a condition in which a person is unable to see well at night or in low light. The retina is a light-sensitive area in the back of the eye and vitamin A deficiency can cause less flow of blood and it is important for the proper functioning of the eye.

So, the correct answer is Option D.
