A
Sympathetic and parasympathetic divisions
B

Verified step by step guidance1
Understand the definition of the central nervous system (CNS): it is the part of the nervous system that processes information and coordinates activity throughout the body.
Recall that the CNS is composed of two main structures: the brain and the spinal cord.
Differentiate the CNS from the peripheral nervous system (PNS), which includes cranial nerves, spinal nerves, and the autonomic divisions (sympathetic and parasympathetic).
Recognize that the sympathetic and parasympathetic divisions are part of the autonomic nervous system, which belongs to the PNS, not the CNS.
Conclude that the correct components of the CNS are the brain and spinal cord, as opposed to peripheral nerves or autonomic divisions.
