impulse begin in a neuron. Thus, the correct option is A.

<h3>How the neuron get stimulus?</h3>

When a neuron receives a chemical stimulation, a nerve impulse is formed. The electrical action potential of the nerve impulse passes along the axon membrane to the axon terminal. Neurotransmitters are released at the axon terminal, which transfer the nerve impulse to the next cell.

The resting potential of a neuron is the electrical differential across its membrane. The sodium-potassium pump, a transport protein, creates the resting potential. This protein generates a positive charge by moving a high number of sodium ions (Na+) outside the cell.
