Answer:

The correct answer will be option C- dorsal root ganglia; Spinal cord.

Explanation:

The cell body of a neuron is the house of cell organelles suspended in the cytoplasm.  

The sensory neuron or afferent neuron transmits the nerve impulse from the receptor to CNS whereas motor neuron or afferent neuron transmits the nerve impulse from the CNS to the tissue.

The cell bodies of a sensory neuron are present in the clusters called ganglia in the dorsal root ganglia from where axons extend in both directions whereas cell bodies of a motor neuron are located in the spinal cord and brain stem.

Thus, option C- dorsal root ganglia; Spinal cord is the correct answer.
