Which of the following statements about resting membrane potential is not true
选项：

A: The resting membrane potential for most animal cells is 0 mV, because the positive and negative ions are in balance.
B: The resting membrane potential for most animal cells is positive, because Na+ ions are so plentiful inside cells.
C: The resting membrane potential for most animal cells is negative, because the inside of the cell is more negatively charged than the outside of the cell.
D: At the resting membrane potential, no ions enter or exit the cell.
