Osmosis refers specifically to the movement of water across a semipermeable membrane from an area of low solute concentration to an area of high solute concentration. Diffusion, on the other hand, is the movement of molecules from an area of high concentration to an area of low concentration. While water can also undergo diffusion, osmosis specifically refers to the movement of water. Therefore, choice D is the correct answer.
