comparatively more permeable to $K^+$ ions and nearly impermeable to $Na^+$ ions.

(D) In the resting state,the axonal membrane of a neuron is significantly more permeable to potassium ions $(K^+)$ due to the presence of leak channels,while it remains nearly impermeable to sodium ions $(Na^+)$.This differential permeability,combined with the action of the $Na^+-K^+$ pump,helps maintain the resting membrane potential.
