Answer:
The correct answer would be option c. 3,2,1.
The correct order for the flow of information in the nervous system would be:
The afferent neurons of the peripheral nervous system (PNS) gather and carry the information or stimulus from the receptors to the central nervous system (CNS; brain and the spinal cord).
The pieces of information are processed and the suitable response is generated in the CNS.
The efferent neurons then carry the response signals from CNS to the associated glands or muscles.
The muscles or glands then produce the response in the form of movement, release or inhibition of hormones et cetera.
