The fibrous white layer that gives the eye its shape is the?

The correct answer is C, sclera, because the sclera is the outermost layer of the eye that provides structural support and shape. It is a tough, fibrous tissue that helps protect the inner components of the eye and maintains its form. The sclera is often referred to as the "white part" of the eye, and it plays a critical role in anchoring the muscles that move the eye.

In contrast, the iris is the colored part of the eye that controls the size of the pupil and thus the amount of light that enters the eye. The cornea is the transparent front part of the eye that covers the iris and pupil, allowing light to enter while also helping to focus it. The choroid is a vascular layer of the eye located between the sclera and the retina, providing nourishment to the retina and absorbing excess light to reduce reflection within the eye. While all these structures are essential for eye function, the sclera is specifically responsible for maintaining the shape and providing protection to the eyeball.
