Question

cdquestions Admin · Accepted Answer

The correct answer is: Option 4: Arthropods Explanation: Arthropods possess a variety of respiratory organs depending on the class and environment they inhabit. For example: Gills are found in aquatic arthropods like crustaceans (e.g., crabs and lobsters). Book gills are found in some arachnids like horseshoe crabs . Book lungs are found in some arachnids like spiders . Trachea is a respiratory system in insects , where air tubes deliver oxygen directly to tissues. The other options are incorrect because: Annelids (Option 1) mainly have skin or gills for respiration (e.g., earthworms). Sponges (Option 2) do not have specialized respiratory organs; they rely on water flow to exchange gases. Molluscs (Option 3) generally have gills (e.g., in aquatic mollusks) or lungs (e.g., in terrestrial snails). Thus, arthropods are the group with diverse respiratory organs like gills, book gills, book lungs, and trachea.
