Assertion: Animals that have an exoskeleton, lacks an endoskeleton.
Reason: Skeleton cells in the embryonic stage migrate to either stage and produce exoskeleton or endoskeleton but never both.
- 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.
Correct answer is option 'D'. Can you explain this answer?

Assertion Analysis
The assertion states that "Animals that have an exoskeleton lack an endoskeleton." This is indeed misleading because:
- Many animals with exoskeletons, such as arthropods (e.g., insects, crustaceans), do not possess an endoskeleton, which is correct.
- However, not all animals that lack an endoskeleton can be categorized solely as having an exoskeleton, as some organisms can have neither.
Reason Analysis
The reason provided states that "Skeleton cells in the embryonic stage migrate to either stage and produce exoskeleton or endoskeleton but never both." This claim is also incorrect because:
- Many organisms do not develop either type of skeleton.
- The process of skeleton development is more complex than a binary choice between exoskeleton or endoskeleton.
Conclusion
Based on the above analyses:
- Both the assertion and the reason are false.
- Therefore, the correct answer is option 'D': If both Assertion and Reason are false.
Key Takeaways
- Exoskeletons and endoskeletons represent different structural adaptations in animals.
- Not all animals neatly fit into the categories of having one or the other.
- The development of skeletal structures is a nuanced process that does not conform to the simplistic explanation provided in the reason.
