  2. BChromatography
  3. CDistillation
  4. DSublimation

Correct answer

B. Chromatography

Step-by-step solution

Adsorption chromatography is the oldest type of chromatography technique. It makes use of a mobile phase which is either in liquid or gaseous form. The mobile phase is adsorbed onto the surface of a stationary solid phase. Adsorption Chromatography involves the analytical separation of a chemical mixture based on the interaction of the adsorbate with the adsorbent. The mixture of gas or liquid gets separated when it passes over the adsorbent bed that adsorbs different compounds at different rates.
