Options

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

Answer

To solve the assertion-reason question, we will analyze both statements step by step.

### Step-by-Step Solution:

1. **Understanding the Assertion**:
- The assertion states: "Bhojpatra is derived from the bark of Betula."
- **Analysis**: Bhojpatra, also known as birch paper, is indeed made from the bark of the Betula tree, specifically Betula utilis, which is commonly known as the Himalayan Birch. This statement is true.

2. **Understanding the Reason**:
- The reason states: "Eucalyptus belongs to the family Myrtaceae."
- **Analysis**: Eucalyptus is a genus of flowering trees and shrubs that are indeed classified under the family Myrtaceae. This statement is also true.

3. **Determining the Relationship**:
- Now we need to determine if the reason provided is the correct explanation for the assertion.
- The assertion and reason are both true, but they refer to different plants (Bhojpatra from Betula and Eucalyptus from Myrtaceae). Therefore, the reason does not explain the assertion.

4. **Conclusion**:
- Both the assertion and the reason are true, but the reason is not the correct explanation of the assertion. Thus, the correct answer is that both statements are true, but the reason does not support the assertion.

### Final Answer:
Both assertion and reason are true, but the reason is not the correct explanation of the assertion.
