Solution
The correct option is A Cones
Rods and cones are the secondary photoreceptors that are present buried under the layer of blood vessels and nerve fibres throughout the retina. Rods are the light sensitive cells that lack colour discrimination. Cones are present primarily in fovea and are stimulated by bright light. Human and other primates have three different types of cone cells for color perception; blue, green and red. Collection of neuronal cell bodies outside the CNS constitutes ganglion cells. Ganglion cell fibres from innermost layer of retina constitute the optic nerve and serves to transmit impulse to brain. The middle neuronal layer of retina has bipolar cells which receive input from photoreceptors (rods and cones) and synapse with ganglion cells. Therefore, the correct answer is option A.
