The correct Answer is:
**Step-by-Step Solution:** 1. **Understand the Question**: The question asks what annelids are classified as. 2. **Identify the Options**: The options provided are: - Flatworms - Roundworms - Six-legged invertebrates - Segmented worms 3. **Analyze Each Option**: - **Flatworms**: These belong to the phylum Platyhelminthes, which is distinct from annelids. - **Roundworms**: These belong to the phylum Aschelminthes (or Nematoda), which is also different from annelids. - **Six-legged invertebrates**: This term refers to insects, which belong to the phylum Arthropoda. Again, this is not related to annelids. - **Segmented worms**: Annelids are indeed classified as segmented worms, characterized by their body structure divided into segments. 4. **Conclusion**: Based on the analysis, the correct classification for annelids is "segmented worms." 5. **Final Answer**: Annelids are segmented worms. ---
