Answer: (D)

Central nervous system

• The central nervous system consists of the brain and spinal cord. It extends from the medulla oblongata in the brainstem to the lumbar region of the vertebral column. It is protected by meninges.
• The peripheral nervous system (PNS) is the division of the nervous system containing all the nerves that lie outside of the central nervous system (CNS).
• The autonomic nervous system controls involuntary actions such as heart rate, digestion, respiratory rate, pupillary response, urination, and sexual arousal.
• The somatic nervous system is the part of the peripheral nervous system associated with the voluntary control of body movements.

So, the correct answer is 'Central nervous system'.
