Solution

The correct option is C Pupil
The pupil is a hole or aperture in the middle of the iris. Iris is the colored part of the eye that controls the amount of light entering the eye by adjusting the size of the pupil. The point of exit of optic nerve from eye forms a “blind spot” in the retina. The sclera is the white and opaque outer layer of the eyeball.
