Solution

The correct option is B Na+ into the cell
In the resting nerve fibre, the cytoplasm inside the axon has a high concentration of K ions and a low concentration of Na ions, in contrast to the fluid outside the axon. Thus if diffusion occurs, then through concentration gradient, Na ions would enter the nerve cells.
