Assertion :- On adding NACl to water its vapour pressure increases.
Reason :- Addition of non-volatile solute increases the vapour pressure.

A

If both assertion and reason are true and the reason is the correct explanation of the assertion.

B

If both assertion and reason are true but reason is not the correct explanation of the assertion.

C

If assertion is true but reason is false.

D

If the assertion and reason both are false.

Text Solution
