76. Colour is perceived by a.cones in retina b.cornea-lens complex c.lense only d.rods in retina
Correct option is B) The retina is a layered structure with several layers of neurons interconnected by synapses. The only neurons that are directly sensitive to light are the photoreceptor cells. These are mainly of two types, the rods and cones. Rods function mainly in dim light and provide black-and-white vision, while cones support the daytime vision and the perception of colour. Thus, the correct answer is option B.
