Answer: chromatography
Step-by-step explanation: Distillation is a purifying technique for two miscible liquids whose boiling points differ by more than 10 degree Celsius.
Chromatography is a purifying technique used for components in a mixture. It is based on the difference in the relative affinities of components towards mobile and stationary phase. To perform ink chromatography, a small dot of ink is put on a strip of filter paper. This end of the paper strip is placed in a solvent called as mobile phase.The solvent moves up the paper strip as it travels upward, it dissolves the components of ink and make the components of ink move with it.The components that dissolve best in the solvent will move at a faster rate than the ones which don't dissolve in solvent and thus can be separated.
Filtration is a purifying technique used for separating a mixture of solid and liquid using a filter paper which does not let the solutes pass and thus can be separated.
Evaporation is a purifying technique used for separating a mixture of non volatile solid and liquid in which liquids vaporizes to gaseous form and the solid remains.
