C. sclerotic
D. iris

Answer

B

Explanation

Retina consists of a pigmented layer and a nervous tissue layer, first there is the photoreceptor layer containing photosensitive cells, the rods and conces. Rod cells are sensitive towards light and are used for vision in dim light, having no ability to detect colour, whereas cones are used for bright light vision with the ability to make coloured images of the object. Next is the intermediate layer containing short sensory bipolar neurons. Bipolar cells inturn synapse with the retinal ganglion cells, whose axons bundle together as the optic nerve.
