Solution

The correct option is B Both Statement I and Statement II are true
Mixture of chloroform and aniline can be separated by simple distillation as these two liquids have sufficient difference in boiling point: Chloroform (b.p. $334 K$ ), aniline (b.p. $457 K$ ).

In steam distillation, if one of the substances is water and the other, a water insoluble substance (like aniline) then the mixture will boil close to but below $373 K .$
