If photoreceptor cells of the retina do not work properly, why will visual information not reach the brain correctly?

Answer and explanation

Correct answer: Because they convert light into nerve signals

The governing concept is sensory transduction in vision. Light entering the eye is focused on the retina, where photoreceptors such as rods and cones absorb light and initiate electrical nerve signals. These signals are carried through retinal neurons and the optic nerve to the brain for interpretation. If photoreceptors fail, the first conversion step is disrupted, so later visual processing cannot receive accurate information. Thus option A is correct; the other choices concern unrelated body functions.
