Assertion: Paper chromatography is a type of partition chromatography.
Reason: Moving phase is liquid and stationary phase is solid.

Options

A. If both assertion and reason are true and reason is the correct explanation of assertion
B. If both assertion and reason are true but reason is not the correct explanation of assertion
C. If assertion is true but reason is false.
D. If both assertion and reason are false.

Explanation

To solve the assertion-reason question, we need to analyze both the assertion and the reason provided.

### Step 1: Understand the Assertion
The assertion states that "Paper chromatography is a type of partition chromatography."
- **Explanation**: Paper chromatography involves the separation of components in a mixture based on their different affinities towards a stationary phase (the paper) and a mobile phase (the solvent). In partition chromatography, the separation occurs due to the distribution of the components between two phases, which aligns with the principles of paper chromatography.

### Step 2: Understand the Reason
The reason states that "Moving phase is liquid and stationary phase is solid."
- **Explanation**: In paper chromatography, the mobile phase is indeed a liquid (the solvent), and the stationary phase is solid (the paper, which is primarily made of cellulose). This statement accurately describes the phases involved in paper chromatography.

### Step 3: Determine the Correctness of Both Statements
- **Assertion**: True, as paper chromatography is indeed a type of partition chromatography.
- **Reason**: True, as the moving phase is liquid and the stationary phase is solid.

### Step 4: Analyze the Relationship Between Assertion and Reason
The reason provides a correct explanation for the assertion. The fact that the moving phase is liquid and the stationary phase is solid helps to clarify why paper chromatography is classified as a type of partition chromatography.

### Conclusion
Both the assertion and reason are correct, and the reason is the correct explanation of the assertion.

### Final Answer
Both the assertion and reason are correct, and the reason is the correct explanation of the assertion.
