Answer 1

Answer:

(B) all are part of the PNS

The peripheral nervous system consists of the part of the nervous system that helps to do the secondary function like carrying to and from the central nervous system (CNS). So senseory neurons and motor neurons are part of peripheral nervous system. The autonomic neurons are responsible for the involuntary action of the body. It is also a part of peripheral nervous system. Though the spinal cord itself is a part of CNS, but the spinal cord neurons which are sensory ,motor and interneurons are part of peripheral nervous system. So all of the options given here are examples of peripheral nervous system.
