Solution
The correct option is A Pupil
Iris is located behind the cornea and is a dark muscular diaphragm that controls the size of the pupil. The pupil regulates and controls the amount of light entering the eye. When bright light falls on the eye the pupil contracts so that less light can enter the eye. However, when dim light falls on the eye the pupil expands so that more light can enter the eye.
