Solution

The correct option is A Na+
Permeability of Na+ ion increases during depolarization due to opening of Na+ ion channels which allow rapid influx of sodium ions into the cell resulting in more positive charge inside the cell and more negative charge outside the cell leading to reversal of polarity.
