The reason that an action potential is so brief is that

a. a wave of repolarization immediately follows the
rising portion of the spike.
b. the closing of potassium gates allows the voltage
difference across the neural membrane to be
restored.
c. the channels for sodium movement remain open.
d. the sodium-potassium pump restores the
electrical gradients.
e. the membrane limits electrical activity.
