Solution

The correct option is A

the direction of impulses.


Based on the direction of flow of impulse neurons are classified to sensory neurons and motor neurons. Sensory neurons carry impulses to the brain and spinal cord from different parts of the body. Motor neurons carry impulses from the brain and spinal cord to different parts of the body.
