Answer 1

The correct answer is option (A).

Peripheral nervous system.

The CNS communicates with the different parts of the body by means of nerves that exit from the brain( cranial nerves) and spinal cord (spinal nerves). The 31 pairs of spinal nerves and the 12 pairs of cranial nerves that arise from CNS, together with aggregations of cell bodies located outside the CNS, constitute the peripheral nervous system (PNS) which carries the messages towards and away from the brain and spinal cord.
