Answer 1

Answer: (C)

The steps involved in the mechanism of vision are as follows:
$1.$ Focusing of the light rays in visible wavelengths on the cornea through the lens.
$2.$ Dissociation of retinal from opsin.
$3.$ Generation of potential difference in photoreceptor cells.
$4.$ Generation of the action potential in ganglion cells through bipolar cells.
$5.$ Transmission of the action potential by the optic nerve to the visual cortex.
$6.$ Analysis of neural impulses and formation of an image on the retina.
