C) depolarization.
D) hypopolarization.

Depolarization

Decrease in electrical charge across a membrane, usually due to the inward flow of sodium ions.

Hyperpolarization

Increase in electrical charge across a membrane, usually due to the inward flow of chloride or sodium ions or the outward flow of potassium ions.
