Assertion:Monoadelphous stamens are found in pea.
Reason:In pea, stamens are united into one bunch or one bundle.

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 assertion and reason are false.

Explanation

To solve the assertion and reason question regarding monoadelphous stamens in pea plants, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Assertion**:
- The assertion states that "Monoadelphous stamens are found in pea."
- Monoadelphous refers to stamens that are united into a single bundle or group.

2. **Understanding the Reason**:
- The reason states that "In pea, stamens are united into one bunch or one bundle."
- This implies that the stamens in pea plants are fused together in a specific manner.

3. **Analyzing the Assertion**:
- In pea plants (Pisum sativum), the stamens are actually in a diadelphous condition, which means they are fused into two bundles, not one.
- Therefore, the assertion is **false** because monoadelphous stamens are not found in pea.

4. **Analyzing the Reason**:
- Since the reason states that stamens are united into one bunch or one bundle, and we know that in pea plants, they are actually united into two bundles, this statement is also **false**.

5. **Conclusion**:
- Both the assertion and the reason are false. Therefore, the correct answer to the question is that both statements are incorrect.

### Final Answer:
- Both the assertion and reason are false.
