Text Solution

Verified by Experts
The correct answer is:
B

If a pressure higher than the osmotic pressure is applied on the solution then reverse osmosis takes place i.e. the solvent will flow from the solution (i.e., high conc. Of solute) into the pure solvent (i.e. low concentration of solute) through the semi permeable membrane.
