A nerve fibre during resting stage is

Options

A. more permeable to `Na^+`
B. more permeable to `K^+`
C. equally permeable for `Na^+ and K^+`
D. less permeable to `K^+`

Answer

B

Explanation

When a neuron is not conducting any impulse, i.e., resting, the axonal membrane is comparatively more permeable to potassium ions `(K^+)` and nearly impermeable to sodium ions `(Na^+)`.
