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.
