Answer 1

The correct option is B

Light sensitive cells on retina get activated wherever light falls and generate electrical signals which are sent to the brain via the optic nerves.

Light sensitive cells on retina get activated wherever light falls on it and generate electrical signals.
These signals are sent to the brain via the optic nerves.
The brain interprets these signals, and finally, processes the information so that we perceive objects as they are.
