The Correct Option is D
Solution and Explanation
P. Centrifugation → 1. Density
Centrifugation separates components based on differences in density under high centrifugal force. Denser particles sediment faster.
Q. Dialysis → 2. Diffusivity
Dialysis relies on diffusion across a semipermeable membrane. Small molecules diffuse out faster due to higher diffusivity.
R. Solvent extraction → 4. Solubility
This method separates components based on differential solubility in two immiscible solvents. Greater solubility allows better extraction.
S. Ultrafiltration → 3. Size
Ultrafiltration membranes retain large molecules and allow smaller molecules to pass through— a size-based separation.
Thus, the matching pattern corresponds to option (D).
