Concept:Vitamin A is essential for the production of pigments in the retina that enable vision.
Explanation:The retina contains light-sensitive cells called rods and cones.
These cells contain visual pigments, such as rhodopsin, which absorb light and trigger nerve signals.
Rhodopsin is formed from a protein called opsin and a light-absorbing molecule derived from vitamin A.
A deficiency in vitamin A reduces the formation of these pigments, leading to poor night vision or night blindness.
Vitamin A is also involved in maintaining the health of the cornea and other eye tissues.
Among the options given, only vitamin A directly supports retinal pigment formation.
Answer:The vitamin important in the formation of the retina pigment is Vitamin A.
Correct option: A. Vitamin A.
