Detailed explanation-1: -The correct option is C osmosis. ∙ Diffusion is the process of movement of materials from a region of higher concentration to lower concentration. ∙ Diffusion of water across a semi-permeable membrane is called osmosis.

Detailed explanation-2: -Osmosis is a passive transport process during which water moves from areas where solutes are less concentrated to areas where they are more concentrated.

Detailed explanation-3: -Osmosis is a specific type of diffusion; it is the passage of water from a region of high water concentration through a semi-permeable membrane to a region of low water concentration.

Detailed explanation-4: -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-5: -Osmosis can be defined as the spontaneous movement of solvent molecules through a semi-permeable membrane from a lower-concentration solution to a higher-concentration solution.
