The correct answer is (B) cornea. The cornea is the transparent outer layer at the front of the eye that covers the iris, pupil, and anterior chamber. It is the first surface that light encounters when entering the eye.
The cornea acts as the eye’s outermost lens, controlling and focusing the entry of light into the eye.
The retina is the light-sensitive tissue lining the back of the eye. The pupil is the opening in the center of the iris that allows light to enter the eye. The iris is the colored part of the eye that controls the size of the pupil.
