Solution

The correct option is D Ciliary muscles
The ciliary muscle is located in the eye and surrounds the lens. It is smooth circular muscle, that relaxes or tightens the zonules to enable the lens to change shape for focusing. When it contracts, it pulls forward, moving to a frontal portion to relax the fibers, that hold the lens in place; this process also allows it to take on a more spherical shape to provide short range focus.
