a
b
c
d

Explanation:

The nervous system is divided into two main parts. The central nervous system (CNS) consists of the brain and spinal cord. The peripheral nervous system (PNS) includes all the nerves outside the CNS. Options A, B, and C mention incorrect components. The parasympathetic nervous system is part of the autonomic nervous system (which is a part of the PNS), and terms like "brain nervous system" and "cranial nervous system" are not the main over - arching components.

Answer:

D. the central nervous system and the peripheral nervous system
