Osmosis is the flow of solution from higher concentration to a solution of lower concentration through a semi permeable membrane. What is incorrect in this statement?

With reference to the movement of molecules of fluid in plant, consider the following statements.
1. Diffusion is the movement of molecules of a substance from the region of their higher concentration to the region of their lower concentration.
2. Osmosis is a process in which the water molecules move through a semipermeable membrane from the region of their lower concentration to the region of their higher concentration.
Which of the statement(s) given above is/are correct ?

A

Only 1

B

Only 2

C

Both 1 and 2

D

Neither 1 nor 2

Assertion (A) In osmosis, solvent molecules pass through a semipermeable membrane from a more dilute solution to a more concentrated one, when these two are separated by the semi-permeable membrane.
Reason (R) The vapour pressure of the solvent over the dilute solution is less than that over the concentrated solution.

A

Both A and R are true and R is the correct explanation of A

B

Both A and R are true, but R is not the correct explanation of A

C

A is true, but R is false

D

A is false, but R is true
