Explanation / Answer

8. B) axon, dendrites and cell body

Nerve cells or neurons are the cells which would be receiving, processing, as well as transmitting information in the form of chemical signals. The basic structure of a neuron is the presence of soma or the cell body, the axons and the dendrite. Dendrites are the structures that would be arising from the body of the cell, which would be extending and branching.
