What method can be used for the separation of two volatile liquids that have a significant difference in their boiling points?

Given below are two statements:
Statement $I :$ $A$ mixture of chloroform and aniline can be separated by simple distillation.
Statement $II :$ When separating aniline from a mixture of aniline and water by steam distillation,aniline boils below its boiling point.
In the light of the above statements,choose the most appropriate answer from the options given below.

When is fractional distillation used?

Draw a diagram showing the setup of the apparatus for the process. Draw a diagram of a bubble plate type fractionating column. When do we require such a type of column for separating two liquids? Explain the principle involved in the separation of components of a mixture of liquids by using a fractionating column. What industrial applications does this process have?

Describe the method,which can be used to separate two compounds with different solubilities in a solvent $S$.

Which of the following is an example of a heterogeneous mixture?
