After the Depolarization Phase of an Action Potential, the Resting

After the depolarization phase of an action potential, the resting potential is restored by

A) the opening of sodium activation gates.
B) the opening of voltage-gated potassium channels and the closing of sodium activation gates.
C) a decrease in the membrane's permeability to potassium and chloride ions.
D) a brief inhibition of the sodium-potassium pump.
E) the opening of more voltage-gated sodium channels.
