Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
The vapour pressure inside the cell is higher than the vapour pressure outside the cell. The fluids present inside the cell come out. Hence, when a cell is placed in hypertonic solution, it shrinks.
During reverse reverse osmosis, solvent from saline water enters the pure solvent through semi-permeable membrane. Hence, reverse osmosis is used for desalination of water.
