The correct Answer is:
To solve the question, we need to analyze each option given in the lists and determine if they are correctly matched based on the organism, its feature, and its respective class. ### Step-by-Step Solution: 1. **Option A: Sea Urchin, Aristotle's Lantern, Echinoidea** - Sea Urchins belong to the class Echinoidea. - They possess a unique feeding structure known as Aristotle's Lantern. - **Conclusion**: This match is correct. 2. **Option B: Sea Cucumber, Respiratory Tree, Holothuroidea** - Sea Cucumbers belong to the class Holothuroidea. - They have a respiratory structure known as the respiratory tree, which helps in gas exchange. - **Conclusion**: This match is correct. 3. **Option C: Sea Biscuit, Anus is Absent, Asteroidea** - Sea Biscuits belong to the class Echinoidea, not Asteroidea. - They do have an anus; hence the feature "anus is absent" is incorrect. - **Conclusion**: This match is incorrect. 4. **Option D: Sea Star, Pedicellaria with Two Jaws, Ophiuroidea** - Sea Stars (or Starfish) belong to the class Asteroidea. - They have pedicellariae, but they are not characterized by having two jaws; this feature is more associated with other classes like Ophiuroidea (brittle stars). - **Conclusion**: This match is incorrect. ### Final Conclusion: The only correct matches are: - Option A: Sea Urchin, Aristotle's Lantern, Echinoidea - Option B: Sea Cucumber, Respiratory Tree, Holothuroidea Thus, the correct answer is **Option A and B**.
