1. Equal amount of Na+ & K+ moves out across axolemma
2. Na+ ions move inside
3. More Na+ ions are outside
4. None of the above

Read the following statements

(A) Depolarization of an axonal membrane is caused due to rise in stimulus-induced permeability to Na+ and its rapid influx into axoplasm.
(B) Diffusion of K+ outside the axonal membrane restores the resting potential of the membrane.
(C) Sodium potassium pump maintains active transport of 2Na+ outwards for 3K+ into axoplasm across resting membrane
