Osmosis is a type of Diffusion of solvent. Imbibition of solution. Evaporation of water. Diffusion of solute.

Osmosis is the movement of water through a semipermeable membrane down the concentration gradient. So, it is a type of diffusion of solvent, not of solute. Imbibition is the absorption of water by a seed or any dry surface. Evaporation refers to the transition of water into the vapor phase. So, the correct answer is option B.
