Answer Key : (a) -

(a)

The plasma membrane of the neuron is polarized due to the high out flow of  ions to outside and low intake of  ion inside.  ions outflow by the ion channel of plasma membrane and  ions inflow by it.

This creates a difference in the positive potential across the plasma membrane. The membrane is less positive inside which is normally termed as negative inside w.r.t outside
