Mobile phase : The mixture is dissolved in a solution is known as mobile phase.

Stationary phase : It is an adsorbent medium and It is a solid, liquid or gel that remains immovable when a liquid or a gas moves over the surface of adsorbent. It remains stationary.

All methods of chromatography are based on the solubility of components of a mixture in a certain solvent.

Hence, the correct option is, (d) All of the above
