The correct option is D hyperpolarized
If the membrane potential becomes more negative than the resting membrane potential or RMP, the membrane is called hyperpolarized. Following the repolarization, there may be a hyperpolarization phase, during which the membrane potential temporarily becomes more negative than the RMP.
During depolarization, the negative membrane potential becomes less negative, reaches 0 and then becomes positive.
During repolarization, the membrane potential is restored to the RMP value of -70mV.
