Which of the following statements is true regarding the fractional distillation of a mixture of two liquids?

The distillate collected is the liquid of lower boiling point is true regarding the fractional distillation of a mixture of two liquids.

Simple distillation cannot be used to separate two liquids if their respective boiling points differ only slightly. Such liquids produce vapours that are simultaneously condensed within the same temperature range. In situations like this, fractional distillation is used. In this method, a fractionating column is used to separate liquid mixture vapours prior to condensation. Over the round-bottom flask's mouth, the fractionating column is affixed. IA) will distil first since it has a low boiling point.

Hence, option A is correct.
