Hyperpolarization means that the membrane potential becomes slightly more negative than the resting potential membrane potential becomes slightly more positive than the resting potential potassium gates open sodium gates open

Option A, membrane potential becomes slightly more negative than the resting potential

Explanation:

Hyper polarization is just opposite of depolarization. In depolarization, the membrane potential becomes slightly positive than the resting potential  while in Hyper polarization the membrane potential becomes slightly more negative than the resting potential.

The v Na+/K+ pump moves the ion against the concentration gradient through the non-gated channels thereby causing the membrane potential more negative.
