The preferable option will be - A.
A. Cornea... lens
Explanation:
As light passes through the eye it is focused by the cornea, which always focuses light in the same way, and the lens, which is flexible and enables focusing on objects at different distances by varying its thickness.
- The cornea mainly allows the light to enter the eye and begins the refractive process, bends the rays through the pupil. The cornea focuses light the most.
- The lens focuses light, refracts the light and show images on the retina. There are ciliary muscles surrounding the lens which contract to allow the lens to change its shape. When these muscles relax one is able to see far away and when they contract, one is able to see up close.
