Correct Option: D
The correct answer is D because Arthropods are characterized by a segmented body.
- A. Radial symmetry: Arthropods exhibit bilateral symmetry, not radial symmetry.
- B. Closed circulatory system: Arthropods have an open circulatory system, not a closed one.
- C. Endoskeleton made of bones: Arthropods possess an exoskeleton made of chitin, not an endoskeleton made of bones.
- D. Presence of a segmented body: This is a defining characteristic of the phylum Arthropoda. Their bodies are divided into segments (e.g., head, thorax, abdomen).
