B Potassium

C Chloride
D Magnesium

Ans. B Potassium
  1. "The magnitude of the resting membrane potential is determined primarily by the concentration of extra cellular K+ because the resting membrane is much more permeable to K+ than it Na+
  2. Changes in the external K+ conc. affect the RMP whereas' change in the external Na+ conc. affect the magnitude of the action potential (Ganong 22nd ed.)
