If light receptors in the eye work but the nerve carrying the message to the brain is damaged, what will happen?
Answer and explanation
Correct answer: Light information will not properly reach the brain
The governing concept is the pathway from receptor to coordinating centre. Photoreceptors can detect light, but the optic nerve must carry the resulting electrical signals toward the brain for visual interpretation. If that nerve is damaged, detection may occur locally but transmission and conscious processing are disrupted. Therefore option A is correct; the other options describe unrelated plant or endocrine claims.
