Final Answer :
D
Explanation :
The iris is the adjustable ring of muscular tissue that controls the amount of light entering the eye by changing the size of the pupil. The lens is responsible for focusing light onto the retina, the cornea is a protective outer layer of the eye, and the retina is the layer of cells at the back of the eye that contains photoreceptor cells.
