Chloroform (b.p. 334K) is mixed with aniline (b.p. 457K). The simplest adequate method of separating the two liquids is
Afractional crystallisation
Bsimple distillation
Csublimation
Dpaper chromatography on a preparative scale
Answer: B
The boiling points differ by 123 K, which is large, so a single simple distillation collects chloroform first and leaves aniline. A fractionating column is not needed.
