The Repolarization of the Neuronal Membrane Is Largely Due to The

The repolarization of the neuronal membrane is largely due to the:

A) closing of calcium channels, stopping the influx of calcium.
B) opening of potassium channels, allowing the outflow of potassium.
C) closing of potassium channels, stopping the influx of potassium.
D) closing of sodium channels, stopping the outflow of sodium.
