C Correct answer
Explanation

Osmosis - is the movement of water from a region of high water concentration or low solute concentration to low water concentration or high solute concentration through a semi-permeable membrane. Thus, osmosis is a special case of diffusion through a semi permeable membrane. (Membrane which allows the entry and exit of only water and not solute). So, it is the correct answer.
