$\text{Adsorption Chromatography involves the analytical separation of a chemical mixture based on the interaction of the adsorbate with the adsorbent.}$ $\text{The mixture of gas or liquid gets separated when it passes over the adsorbent bed that adsorbs different compounds at different rates.}$ $\text{For adsorption chromatography, the adsorbent is used as the stationary phase.}$ $\text{The solute binds to the adsorbent via van der Waal forces and steric interactions.}$ $\text{Since the adsorption sites are typically only on the outer surface of the stationary phase, fairly small particles are used as the stationary phase.}$ $\text{Some commonly used adsorbents are Silica gel H, silica gel G, silica gel N, silica gel S, hydrated gel silica, cellulose microcrystalline, alumina, modified silica gel, etc.}$ $\text{Hence, option 4 is the correct answer.}$
