Question

which layer of the eye contains the sensory receptors for sight?
a retina
b choroid
c sclera
d lens

Explanation:

The retina is the innermost layer of the eye. It contains photoreceptor cells (rods and cones) which are the sensory receptors for sight. These cells convert light into neural signals. The choroid is a vascular layer between the retina and sclera, mainly for blood supply. The sclera is the tough outer layer (the white of the eye). The lens helps focus light onto the retina but does not contain sensory receptors for sight.

Answer:

A. retina
