The correct option is B (a)-(ii), (b)-(iii), (c)-(iv), (d)-(i)
Dye in ink:
The mixture of dye in ink contain the different solute components dissolved in the same solvent. Due to the difference in the solubilities of different components, the mixture can be separated by chromatography.
Oil and water:
Oil and water are two immiscible liquids having difference in their densities. Thus they can be separated by separating funnel.
Wheat grains and husk:
Wheat grains and husk have difference in their densities. Here, one of the component is light enough to be carried away by wind. Thus, they can be separated by the process of winnowing.
Acetone and water:
Acetone and water are two miscible liquids having difference in their boiling points greater than 25 Degree Celsius. Thus, they can be separated by the prosses of simple distillation.
