What Effect Would Increasing the Extracellular Concentration of K+ Have

What effect would increasing the extracellular concentration of K+ have on the resting membrane potential (RMP) ?

A) The RMP would become more positive (less negative) .
B) The RMP would become more negative.
C) The effects are really seen on the generating potential.
D) Increasing extracellular K+ will have no effect on the RMP because it displaces Na+.
E) Increasing extracellular K+ will have no effect on the RMP because of the Na+/ K+ pump.
