Solution

The correct option is D Is brought by afferent fibres and carried by efferent fibres.
Afferent neurons (also known as sensory or receptor neurons) carry nerve impulses from receptors or sense organs toward the central nervous system. Efferent nerves (also known as motor or effector neurons) carry nerve impulses away from the central nervous system to effectors, such as muscles or glands. Hence the correct option is D.
