Hint: The key word in this question is ‘miscible’, which means forming a homogeneous solution. The miscible liquids can be separated by difference in physical properties.

Complete step by step answer:
Two miscible and volatile liquids can be separated into pure components by fraction distillation under the following conditions –
1. they have low boiling points
2. the differences in their boiling points is large
3. the boiling points of the liquids are close to each other
4. they do not from azeotropic mixture

A mixture of two miscible liquids can be separated by the process of fractional distillation. The separation of two liquids by fractional distillation depends on the difference in their boiling points.
Therefore, the answer is option (b) – Miscible liquids can be separated by fractional distillation.

Note: Distillation process is defined as “the process of separating the components or substances from a liquid mixture by using selective boiling and condensation”.
Chromatography is defined as “a technique for the separation of a mixture by passing it in solution or suspension through a medium in which the components move at different rates”.
“A separatory funnel, also known as a separation funnel, separating funnel is a piece of laboratory glassware used in liquid-liquid extractions to separate (partition) the components of a mixture into two immiscible solvent phases of different densities”.
