Correct answer: A

Analyze Statement (I): Partition chromatography

In partition chromatography, separation occurs because components distribute themselves between:
- a stationary liquid phase, and
- a mobile phase.
The stationary phase is typically a thin film of liquid supported on an inert solid support.

Therefore, Statement (I) is true.
Analyze Statement (II): Paper chromatography

In paper chromatography, the paper itself does not act as the stationary phase.

Actually:
- the stationary phase is the water adsorbed/held in the fibers of the paper, and
- the paper acts only as a support.
Hence, saying that the "material of paper acts as a stationary phase" is incorrect.

Therefore, Statement (II) is false.
Evaluate the options
- A: Statement I is true but Statement II is false ✅
- B: Statement I is false but Statement II is true ❌
- C: Both Statement I and Statement II are false ❌
- D: Both Statement I and Statement II are true ❌
Final conclusion

The correct option is: $\boxed{A}$
Comparison with stored correct answer

Stored correct answer = A

My derived answer = A

Hence, they agree.
