D) a positive charge for cells in the central nervous system, and a negative charge for cells in the peripheral nervous system.

Question

Final Answer : B, Explanation :  During the resting potential, the inside of the axon has a negative charge relative to the outside of the cell. This is due to the concentration of negatively charged ions, such as chloride (Cl-) and proteins, inside the cell and positively charged ions, such as sodium (Na+) and potassium (K+), outside the cell. This difference in charge creates an electrical potential difference across the cell membrane, which is maintained by the sodium-potassium pump.
