Answer:
Option B - Repolarization
Step-by-step explanation:
The change in the membrane potential to a negative value just after action potential is known as repolarization phase.
In cell, the depolarization event allows sodium channel to open. The cell after a short period of time allows the event of repolarization. The repolarization event occurs due to outflow of K+ ions. Thus, a damaged neuron will prevent the repolarization event.
