Statement (A) : Mixture of benzene and toluene shows characters of ideal solution. 

Statement (B) : Mixture of water and methanol shows positive deviation from Raoult’s law. 

Statement (C) : Mixture of chloroform and benzene shows negative deviation from Raoult’s law.

Escaping tendency of benzene and toluene should be same in pure liquids and in solution.

Water and methanol escape easily showing higher vapour pressure than the expected value. Escaping tendency of chloroform and benzene is lower showing lower vapour pressure than expected ideally.
