If turgor pressure becomes equal to osmotic pressure

Answer: Option C

If turgor pressure becomes equal to osmotic pressure no exchange of water takes place.
Turgor pressure is the hydrostatic pressure over ambient atmospheric pressure which can build up in living, walled cells. Turgor is generated through the osmotically driven inflow of water into cells across a selectively permeable membrane; this membrane is typically the plasma membrane.
Osmotic pressure is the minimum pressure that needs to be applied to a solution to prevent the inward flow of its pure solvent across a semipermeable membrane.
