What would happen to an action potential if the voltage-gated Na⁺ channels closed earlier than normal? A) The amplitude would be smaller, but the duration would be similar. B) The amplitude would be similar, but the duration would be shorter. C) The amplitude and duration would be similar, but fewer K⁺ channels would open. D) The action potential would remain unchanged.

If the voltage-gated Na⁺ channels close earlier, fewer Na⁺ ions enter the cell, resulting in a smaller amplitude of the action potential, but the duration may remain similar due to the subsequent opening of K⁺ channels.
