Answer:
The correct answer is option A. "the temporary hyperpolarization of the axon membrane following the action potential spike".
Explanation:
Action potentials, also known as "spikes" or "impulses", are electric impulses that neurons use to send information from the cell's body down to the axon. The impulses are created when ions travel across the neuron's membrane creating a depolarization current. This depolarization current is responsible for an temporary hyperpolarization of the axon membrane following the action potential spike. When neurons are hyperpolarized they are not able to produce another action potential. In consequence, actions potentials move in one direction along the neuron away from the cell body, as well as, adjacent locations go trough similar depolarization processes.
