Solution
The correct option is D DOOD
Osmosis is the movement of water molecules from a region of high concentration to a region of low concentration through a semi-permeable membrane. Hence, any passive transport of water across the cell membrane is by the process of osmosis.
Diffusion involves the movement of substances along the concentration gradient. Movement of gases across the membrane is by diffusion.
