__________ are believed to have common origin with annelids.
Correct answer: B. Arthropods
- A. Nematods
- B. Arthropods
- C. Molluscs
- D. None of these
Explanation
Arthropods and annelids are traditionally considered to share a common segmented ancestor, since both show metamerism and similar developmental patterns in classical zoology. Students may choose molluscs because they are also invertebrates, but molluscs do not have the characteristic segmented body plan.
