Go with C — Depolarization. Within Sensory System Ear Physiology, that statement lines up with the standard definition and the usual exam wording you’ll see. In plain terms, Depolarization is the option that correctly names the structure, process, or principle asked for in Sensory System Ear Physiology. Holding that picture in mind makes Depolarization feel natural rather than something you only memorise.

A short mental diagram helps — start from stimulus or structure, follow the pathway, and stop at the functional result described by Depolarization.

If a similar stem appears later, start from the same core fact and you will land on the same kind of answer. In class notes, highlight this same phrase next to the related diagram so the wording and the picture reinforce each other.
