Solution

The correct option is C Assertion is correct but Reason is incorrect
Acetone - Carbon disulphide solution shows a positive deviation from Raoult's law. The observed vapour pressure of each component and total vapour pressure is greater than predicted by Raoult's law.

Acetone + Aniline solution shows a negative deviation from Raoult's law. The observed vapour pressure of each component and total vapour pressure is less than predicted by Raoult's law.

Assertion is correct but Reason is incorrect.
