Solution

The correct option is B Number of processes arising from the cell body
Neurons can be differentiated as unipolar, bipolar or multipolar depending upon the number of processes arising from the cell body.
Unipolar neuron possesses just one process emerging from the cell.
Bipolar neuron possesses two processes. These processes arise from each end of the cell body.
Multipolar shows many processes arising from the cell body.
Therefore, option B is correct.
