The rapid inward diffusion of Na+ followed by the outward diffusion of K+ produces a rapid change in the membr

The answer is E. The influx of sodium due to the opening of voltage-gated channels causes a depolarization of the membrane. This is followed by the inactivation of those channels and the opening of voltage-gated potium channels resulting in an influx of K+ and a repolarization of the membrane. The whole process is called an action potential.
