The correct option is D soma
Neurons are the functional unit of the neural system. They consist of 3 main parts - soma/cellbody, dendrites and axon.
The dendrites are projection from the cell body or soma. It is the receiving part of the neuron. The cell body consists of nucleus, cytoplasm, nissls granules. The Nissls granules are responsible for the protein synthesis. The cell body leads to an elongated portion called the axon. At the terminal end of the axon is a bulbous structure called synaptic knobs.
