The correct option is C Exosmosis
Osmosis is the process of the movement of solvent molecules through a semipermeable membrane from a region of higher solvent concentration to the region of lower solvent concentration. The energy which drives this process is called as osmotic pressure. Osmosis is of great importance in biological processes. If grapes are placed in a salt solution that is more concentrated than cell sap, exosmosis will happen and grapes will shrink.
