B. Fluid outside the axon has a high 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 a charge and its inner surface is positively charged.
