The correct Answer is:
To solve the question, we need to evaluate both the assertion and the reason provided and determine their truthfulness and relationship. ### Step-by-Step Solution: 1. **Understanding the Assertion**: - The assertion states that "Lycaenops is a mammal-like reptile." - This is true because Lycaenops is indeed classified as a mammal-like reptile, which is a group that exhibits characteristics of both mammals and reptiles. 2. **Understanding the Reason**: - The reason states that "Mammal-like reptiles originated in the Permian period." - This statement is also true. Mammal-like reptiles, including Lycaenops, did originate during the Permian period. 3. **Evaluating the Relationship**: - Now we need to determine if the reason correctly explains the assertion. - While both statements are true, the reason does not explain why Lycaenops is classified as a mammal-like reptile. The classification is based on its characteristics, not merely its origin in the Permian period. 4. **Conclusion**: - Since both the assertion and the reason are true, but the reason does not provide a correct explanation for the assertion, the correct choice is (b): "If both Assertion and Reason are true, but the Reason is not the correct explanation of the Assertion." ### Final Answer: (b) If both Assertion and Reason are true, but the Reason is not the correct explanation of the Assertion.
