Answer: c. iris – controls the pupil
Explanation:
The iris, a structure which is primarily made up of smooth muscles. These smooth muscles surrounds the pupil. The light enters the eye through pupil which is a black hole present in the middle of the eye. It allows the light to strike the retina. It controls the size of the pupil this way it helps in regulating the amount of light entering the eye. The pupil becomes wider in the darkness and becomes narrower when the light intensity is more. These actions are controlled by iris.
