What does the motor division do?
A
Send signals within your Brain
B
It drives the neurons
C
Send signals from your ears to the CNS
D
Send signals from the CNS to Muscles
Explanation: 

Detailed explanation-1: -The motor (efferent) division carries motor signals by way of efferent nerve fibers from the CNS to effectors (mainly glands and muscles). It can be further subdivided into somatic and visceral divisions. The somatic motor division carries signals to the skeletal muscles.

Detailed explanation-2: -The afferent division of the peripheral nervous system carries impulses to the CNS; the efferent division carries impulses away from the CNS. There are three layers of meninges around the brain and spinal cord.

Detailed explanation-3: -Motor nerves act as efferent nerves which carry information out from the CNS to muscles, as opposed to afferent nerves (also called sensory nerves), which transfer signals from sensory receptors in the periphery to the CNS.
