Question

What are the functions of Vitamin A?
(A) Blood coagulation
(B) Immunity
(C) Forming Epithelium
(D) Acts as coenzyme
(E) Produces Rhodopsin
Choose the most appropriate answer from the options given below:

• (A) and (B) only
• (C) and (E) only
• (B) and (D) only
• (C) and (D) only

Hint:

Think A for epithelium and eyes — Vitamin A = skin + night vision.

Answer 1

The Correct Option is B

Vitamin A has several key functions in the body.
It plays an essential role in the formation and maintenance of healthy epithelium — epithelial tissues need Vitamin A for integrity and regeneration.
It is also crucial for the synthesis of Rhodopsin, a light-sensitive pigment in the retina that is necessary for vision in low-light conditions.
Blood coagulation is a function of Vitamin K, not Vitamin A.
Immunity is indirectly supported by Vitamin A but is not its primary direct function in this context.
Acts as coenzyme is more related to B-complex vitamins.
Therefore, the correct functions are Forming Epithelium and Producing Rhodopsin.
