When a neuron is in a resting state,i.e.,not conducting any impulse,the axonal membrane is:

  • A
    Comparatively more permeable to $Na^+$ ions and nearly impermeable to $K^+$ ions.
  • B
    Equally permeable to both $Na^+$ and $K^+$ ions.
  • C
    Impermeable to both $Na^+$ and $K^+$ ions.
  • D
    Comparatively more permeable to $K^+$ ions and nearly impermeable to $Na^+$ ions.
