NikAS [45]

The correct answer is option B

A motor neuron is a neuron which consists of a cell body and axon. Cell body lies in the motor cortex, spinal cord or brainstem and axon projects outside the spinal cord or inside the spinal cord which directly or indirectly controls the function of muscles or glands.
