Q. No.In a comparative zoology study of body cavity, symmetry, and development patterns, which statement correctly integrates multiple phyla characteristics?
| 1. | Pheretima (Annelida) is coelomate, metamerically segmented with closed circulatory system; Pila (Mollusca) is coelomate with closed circulation and radula; Limulus (Arthropoda) lacks metameric segmentation |
| 2. | All coelomates show bilateral symmetry and triploblastic organisation; Taenia is acoelomate, endoparasitic; Ancylostoma is pseudocoelomate with complete digestive system |
| 3. | Adamsia (Cnidaria) shows radial symmetry, diploblastic with cnidoblasts; Planaria (Platyhelminthes) shows bilateral symmetry, triploblastic, acoelomate with flame cells; Ascaris (Aschelminthes) is pseudocoelomate, dioecious |
| 4. | Echinoderms show bilateral symmetry in adults with coelomic water vascular system; hemichordates have notochord throughout life; both show deuterostome development |
