Which of the following statements is wrong regarding conduction of nerve impulse ?

Options

A. In a resting neuron, the axonal membrane is more permeable to `K^+` ions and nearly impermeable to Naions.
B. Fluid outside the axon has a high concentration of Nations and low concentration of `K^+`,in a resting neuron.
C. Ionic gradients are maintained by Na-K pumps across the resting membrane, which transport `3Na^(+)` ions outwards for `2K^(+)` into the cell.
D. A neuron is polarized only when the outer surface of the axonal membrane possess a negative charge and its inner surface is positively charged.

Explanation

A neuron is polarized only when the outer surface of the axonal membrane possess a negative charge and its inner surface is positively charged.
