E) lens.

A

Answer: C. Cornea.

Explanation: In the human eye, most refraction occurs when light passes through the cornea, as the cornea is the first medium through which light travels before it travels further into the eye.

The cornea is the curved, transparent layer of the eye and the site for the most ocular refraction.

Refraction also occurs in the lens of the eyes, but most of it happens in the cornea.
