Which of the following best explains why the plasma membranes of all cells exhibit a negative resting potential? (A) The membrane is mostly permeable to Cl", and the Cl- gradient favors its diffusion out of the cell. (B) The membrane is mostly permeable to K*, and the K* gradient favors its diffusion into the cell. (C) The membrane is mostly permeable to K*, and the K* gradient favors its diffusion out of the cell. (D) The membrane is mostly permeable to Na*, and the Na* gradient favors its diffusion into the cell. (E) The membrane is mostly permeable to Na*, and the Na* gradient favors its diffusion out of the cell.
