the main divisions of the central nervous system are the:
○ brain, spinal cord, and autonomic nerves.
○ brain, spinal cord, and peripheral nerves.
○ brain and spinal cord.
○ sensory division and motor division.

Explanation:

To solve this, recall the structure of the central nervous system (CNS). The CNS consists of the brain and spinal cord. Autonomic nerves and peripheral nerves are part of the peripheral nervous system (PNS). The sensory and motor divisions are part of the PNS's functional divisions. So the correct option is the one with just brain and spinal cord.

Answer:

C. brain and spinal cord. (Assuming the options are labeled A, B, C, D with C being "brain and spinal cord" as per the options shown: A. brain, spinal cord, and autonomic nerves; B. brain, spinal cord, and peripheral nerves; C. brain and spinal cord; D. sensory division and motor division)
