Assertion (A) When solution is separated from the pure solved by a semipermeable membrane, the solvent molecules pass through it from pure solvent side to the solution side.
Reason (R ) Diffusion of solvent occurs from a region of high concentration solution to a region of low concentration solution

Options

A. Assertion and reason both are correct statements and reason is correcft explanation for assertion.
B. Assertion and reason both are correct statements but reason is not correct explanation for assertion.
C. Assertion is correct statement but reason is wrong statement.
D. Assertion and reason both are incorrect statements.

Answer

b

Explanation

Assertion and reason both are correct statement but reason is not the correct explanation of assertion.
When a solution is separted from the pure solcent by a semipermeable membrane, the solvent molecules pass through it from pure solvent side to the solution side. Solvent molecules always flow from lower concentration to higher concentration of solution.
