The correct Answer is:
**Step-by-Step Solution:** 1. **Identify the Features**: The question mentions three specific features: carapace, green glands, and cephalothorax. We need to understand what each of these features represents. 2. **Define Carapace**: A carapace is a hard protective shell found in certain animals, particularly in crustaceans like crabs and lobsters. It serves as a protective covering for the body. 3. **Define Green Glands**: Green glands are excretory organs found in some arthropods, specifically in crustaceans. They help in the excretion of waste materials. 4. **Define Cephalothorax**: The cephalothorax is a body structure where the head and thorax are fused together. This is characteristic of certain groups of arthropods. 5. **Analyze the Options**: The question likely provides multiple options. We need to evaluate which group of animals possesses all three features mentioned. 6. **Evaluate Crustacea**: Crustaceans, which include lobsters, prawns, and crabs, exhibit all three features: - They have a carapace (hard covering). - They possess green glands (excretory organs). - Their body structure includes a cephalothorax (fused head and thorax). 7. **Evaluate Other Options**: - **Chilopoda** (centipedes) and **Diplopoda** (millipedes) do not have a carapace or cephalothorax as their bodies are segmented into distinct head, thorax, and abdomen. - **Insecta** also has a segmented body with distinct head, thorax, and abdomen, lacking a cephalothorax. 8. **Conclusion**: Based on the analysis, the correct answer is **Crustacea**, as it is the only group that possesses all three features: carapace, green glands, and cephalothorax. ---
