Answer:

B

Explanation:

Depolarization occurs by the opening of K+ voltage gated channels that cause K+ to leave the cell down a chemical gradient. This makes the inside of the cell less positive until there's reversal of polarity and eventually the resting potential is generated at -70 mV.

This is helped by ATP dependent Na+-K+ pumps.
