Vedclass · Answer

(B) During the repolarization phase of an action potential,the membrane potential returns to its resting state.This process is triggered by the inactivation of voltage-gated $Na^+$ channels,which stops the influx of $Na^+$ ions.Simultaneously,voltage-gated $K^+$ channels open,allowing $K^+$ ions to diffuse out of the neuron.This efflux of positive $K^+$ ions restores the negative charge inside the membrane relative to the outside,thus completing repolarization.
