The initial event of an action potential is the depolarization of the axon due to the inflow of sodium ions. Thus, the option c is correct.
the action potential occurs. The membrane potential at which the action potential occurs is called the threshold for the nerve or muscle fiber. The action potential differs from the local response in that it is a much larger response (the polarity of the cell membrane actually reverses, the cytosol becoming positive with respect to the extracellular fluid) and an action potential is propagated without decrement down
