Explanation:

The nervous system has two main parts: the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS is made up of the brain and spinal cord. The PNS consists of nerves outside the CNS. "Efferent" refers to motor neurons carrying signals away from the CNS. "Afferent" refers to sensory neurons carrying signals to the CNS. The "autonomic" nervous system is a part of the PNS that controls involuntary functions. So the brain and spinal cord are the central nervous system.

Answer:

C. central
