Assertion : If a liquid solute more volatile than the solvent is added to the solvent, the papour pressure of the solution may increase i.e. `p_s gt p^@.`
Reason In the presence of a more volatile liquid solute, only the solute will form the vapours and solvent will not.

Options

A. If both (A) and (R) are correct and (R) is the correct explanation of(A).
B. If both (A) and (R) are correct, but (R) is not the correct explanation of (A).
