The Correct Option is A
Solution and Explanation
Concept:
Paper chromatography separates substances on the basis of partition of solute between two liquid phases.
The stationary phase is water adsorbed on cellulose fibres of paper and the mobile phase is a suitable organic solvent.
Thus, both phases involved are liquids.
Step 1: Check Statement I.
Statement I says paper chromatography is adsorption chromatography. This is incorrect. Adsorption chromatography involves a solid stationary phase such as silica gel or alumina. Therefore Statement I is false.
Step 2: Check Statement II.
Paper chromatography is based on partition of solute between two liquid phases. Hence Statement II is correct.
Step 3: Check Statement III.
Stationary phase: \[ \text{Water adsorbed on paper} \] Mobile phase: \[ \text{Organic solvent} \] Both are liquids. Hence Statement III is correct.
Step 4: Check Statement IV.
The stationary phase is not solid. Therefore Statement IV is incorrect. Thus the correct statements are \[ II \text{ and } III \] \[ \boxed{\text{Option (A)}} \]
