Polarized because the inside of the cell is more negatively charged than the outside of the cell
Depolarized because the inside of the cell is more positively charged than the outside
Non-Polar because the charge on both sides of the membrane are equal
Neutral because there is no difference in the concentrations of the Na+ and K+ ions

It is polarized.
In a resting state, the neuron is ready to fire, but not currently doing so. The set up would be more sodium on the outside (positively charged) and more chloride on the inside (negatively charged).
Depolarized would indicate that the neuron just fired, and is in its refractory period; not at its resting potential.
Non-polar is not right because a charge is needed to pass on an electric signal.
Neutral is wrong because there are plenty more Na+ ions than K+ ions. In the sodium-potassium pump, three sodiums are pumped out for two potassiums to come in. Because it is an uneven change, the net charge within the axon drops significantly.
