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 `Na^(+)` ions.
B. Fluid outside the axon has a high concentration of `Na^(+)` ions and low concentration of `K^(+)` in a resting neuron
C. Ionic gradient s 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 a charge and its inner surface is positively charged.
