Detailed explanation-1: -Osmosis is a process of movement of solvents through a semi-permeable membrane from a region of lower solute concentration to higher solute concentration. On the contrary, diffusion does not require a semi-permeable membrane to occur and the molecules move from a region of higher concentration to lower concentration.

Detailed explanation-2: -Osmosis is the movement of water across a semi-permeable membrane from an area of low solute concentration to an area of high solute concentration. Osmosis helps regulate the flow of water in and out of cells, which is crucial to their function.

Detailed explanation-3: -Osmosis is the diffusion of water where molecules of water move passively (without energy) from high concentration to low concentration. A good example would be the way water rushes into a sponge, when a dry sponge is placed in a pan of water.

Detailed explanation-4: -So, the correct answer to the above question is ‘movement of a solvent through a semipermeable membrane’.
