Explanation:
The central nervous system comprises the brain and spinal cord, which are the main command and processing centers of the nervous system. The brain includes regions like the cerebrum and cerebellum, so referring to the brain covers these parts. The meninges are protective membranes surrounding the brain and spinal cord, not CNS tissue themselves, so including them would be inaccurate. A description that pairs the spinal cord with meninges omits the brain, which is essential to the CNS. Therefore, the brain and spinal cord best describe the CNS.
