A
the brain, only
B
the brain and spinal cord
C
the brain, spinal cord, and spinal nerves
D
the brain and cranial nerves
Explanation: 

Detailed explanation-1: -The central nervous system (CNS) is made up of the brain and spinal cord. It is one of 2 parts of the nervous system. The other part is the peripheral nervous system, which consists of nerves that connect the brain and spinal cord to the rest of the body. The central nervous system is the body’s processing centre.

Detailed explanation-2: -Broadly speaking, the nervous system is organised into two main parts, the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS is the processing centre of the body and consists of the brain and the spinal cord. Both of these are protected by three layers of membranes known as meninges.

Detailed explanation-3: -The spinal cord is an extension of the central nervous system (CNS), which consists of the brain and spinal cord.

Detailed explanation-4: -Central Nervous System Structure. The CNS has three main components: the brain, the spinal cord, and the neurons (or nerve cells). Each part of the CNS plays an important role in how the body functions, and the three components of the CNS work together to take in information and control how the body responds.

Detailed explanation-5: -Cranial nerves and spinal nerves extend from the CNS to peripheral organs such as muscles and glands. Ganglia are collections, or small knots, of nerve cell bodies outside the CNS. The peripheral nervous system is further subdivided into an afferent (sensory) division and an efferent (motor) division.
