Question
Assertion: When a solution is separated from the pure solvent by a semipermeable membrane, the solvent molecules pass through it from pure solvent side to the solution side.
Reason: Diffusion of solvent occurs from a region of high concentration solution to a region of low concentration solution.
Options
Assertion and reason both are correct statements and reason is correct explanation for assertion.
Assertion and reason both are correct statements but reason is not correct explanation for assertion.
Assertion is correct statement but reason is wrong statement.

Solution
Assertion and reason both are correct statements but reason is not correct explanation for assertion.
Explanation:
The Assertion is correct because it describes osmosis - solvent moves from pure solvent (high solvent concentration) to solution (low solvent concentration) through a semipermeable membrane.
The Reason is wrong because solvent does not move from high concentration solution to low concentration solution; it moves from high solvent concentration to low solvent concentration.
