When a neuron is in resting state i.e., not conducting any impulse, the axonal membrane is:
 
1. equally permeable to both Na+ and K+ ions
2. impermeable to both Na+ and K+ ions
3. comparatively more permeable to K+ ions and nearly impermeable to Na+ ions
4. comparatively more permeable to Na+ ions and nearly impermeable to K+ ions
