Assertion: Breaking of rocks is called weathering.
Reason: Weathering of rocks is due to physical and chemical methods.

Options

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

Explanation

### Step-by-Step Text Solution:

1. **Understanding the Assertion**:
- The assertion states that "breaking of rocks is called weathering."
- This is a true statement, as weathering is defined as the process that breaks down rocks into smaller particles.

2. **Understanding the Reason**:
- The reason provided is that "weathering of rocks is due to physical and chemical methods."
- This statement is also true. Weathering can occur through various processes, primarily categorized into physical (mechanical) and chemical weathering.

3. **Explaining Physical Weathering**:
- Physical weathering involves the breakdown of rocks without changing their chemical composition.
- Examples include the action of ice, running water, wind, rapid heating and cooling, and plant growth.

4. **Explaining Chemical Weathering**:
- Chemical weathering involves the alteration of the chemical structure of rocks, leading to their breakdown.
- This can occur through reactions between the minerals in the rocks and substances such as water, acids, or gases, which can dissolve parts of the rock.

5. **Conclusion**:
- Since both the assertion and the reason are true, and the reason accurately explains the assertion, the correct answer is that both the assertion and reason are true, and the reason is the correct explanation of the assertion.

### Final Answer:
Both assertion and reason are true; the reason is the correct explanation of the assertion.
