What is influx of ions?

Given below are the steps involved in the generation and conduction of nerve impulse. Arrange them in proper sequence and select the correct option. I. Rapid influx of Na^+ ions followed by reversal of polarity at the site of application of stimulus. II. Reversal of polarity and generation of action potential at a point ahead of the point of application of stimulus. III. Development of free permeability to Na^+ ions at the site of application of stimulus. IV. Arrival of the impulse generated at the first site to the second site. V. Rise in permeability of K^+ ions and restoration of the resting potential of the membrane.
