What Effect on a Neuron's Resting Potential Would a Drug

What effect on a neuron's resting potential would a drug that stop sodium-potassium pump activity likely have?

A) The neuron's resting potential would be unaffected.
B) The neuron's resting potential would become hyperpolarized due to decreasing in potassium ions.
C) The neuron's resting potential would become depolarized due to a increase in sodium ions.
D) The neuron would not be able to produce an action potential.
