E)Keratin

Accepted Answer

Crystallins are the proteins that make up the refractive portion of the lens. They are responsible for the transparency of the lens and play a crucial role in focusing light onto the retina. Collagen, elastin, and keratin are structural proteins found in other parts of the body, while ciliary bodies are responsible for producing aqueous humor in the eye.
