Assertion : Pneumotaxic centre is situated in Pons
Reason: It can regulate the functioning of rhythm centre

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.

Answer

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

### Step-by-Step Solution:

1. **Understanding the Assertion**:
- The assertion states that the pneumotaxic center is situated in the pons.
- This is true. The pneumotaxic center is indeed located in the pons region of the brainstem.

2. **Understanding the Reason**:
- The reason states that the pneumotaxic center can regulate the functioning of the rhythm center.
- This is also true. The pneumotaxic center helps regulate the rhythm of breathing by influencing the respiratory rhythm center located in the medulla.

3. **Evaluating the Relationship**:
- While both the assertion and reason are true, we need to determine if the reason correctly explains the assertion.
- The assertion is about the location of the pneumotaxic center, while the reason discusses its function in relation to the rhythm center.
- The reason does not directly explain why the assertion is true; it merely states a related fact.

4. **Conclusion**:
- Both the assertion and reason are true statements, but the reason is not the correct explanation for the assertion.
- Therefore, the correct answer to the question is that both statements are true, but the reason is not the correct explanation for the assertion.

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