Answer 1

The correct option is C

Brain and Spinal cord

The Human neural system is divided into two parts – central nervous system (CNS) and peripheral nervous system (PNS).

The CNS includes brain and spinal cord. It is the site of information processing and control.

The PNS comprises of all the nerves that innervate the different body parts and organs.

The main function of the PNS is to connect the CNS to the limbs and organs, essentially serving as a relay between the brain and spinal cord and the rest of the body.
