What does the ciliary body in the eye do?

Correct option is C

Ans: (c) Change the shape of the lens to focus light Sol. The ciliary body is part of the eye's middle layer and plays a crucial role in adjusting the shape of the lens to focus light on the retina. This process is known as accommodation. The ciliary muscles within the ciliary body contract or relax to change the curvature of the lens, allowing for focusing on objects at various distances.
Explanation of each option:
· (a) Filter out harmful UV radiation: The ciliary body does not filter UV radiation. The cornea and lens help protect the eye from UV light. The ciliary body is involved in lens shape adjustment, not UV protection.
· (b) Replaces damaged retina cells: The ciliary body does not replace retina cells. The retina is responsible for detecting light and converting it into electrical signals, but it does not rely on the ciliary body for cell replacement.
· (d) Detect light and convert it into electrical signals: This is the function of the retina, not the ciliary body. The retina contains photoreceptor cells that detect light and send electrical signals to the brain.
