The correct options are

Imbibition is the process of adsorption of water by solids - colloids - causing them to increase in volume. It is a special type of diffusion. Due to imbibition, the volume of wood increases during rainy season and it swells. Seeds also adsorb water, which helps in breaking the seed coat and allows the seedling to emerge out of the seed. Raisins also swell up due to adsorption of water.
