Solution

The correct option is C Changes the size of the pupil to regulate light
Aqueous humour is the clear liquid inside the front part of the eye. It nourishes the eye and keeps it inflated. It is formed from the blood by filtration, secretion, and diffusion through the ciliary body. It protects the eye and also bends light to aid in focusing light from the source.
And iris is the structure that regulates the amount of light entering the eye by controlling the size of the pupil.
