In paper chromatography:

Options

  1. AMobile phase is liquid and stationary phase is solid.
  2. BMobile phase is solid and stationary phase is liquid.
  3. CBoth phases are liquids.
  4. DBoth phases are solids.

Correct answer

C. Both phases are liquids.

Step-by-step solution

Paper chromatography is a special case of partition chromatography where the special quality paper containing water trapped in it acts as a stationary phase and solvent as a mobile phase. Thus, both phases are liquids.
