The correct Answer is:
To solve the question regarding the segmental appendages of Nereis, we can follow these steps: ### Step-by-Step Solution: 1. **Identify the Organism**: Nereis is a genus belonging to the phylum Annelida, which includes segmented worms. 2. **Understand the Structure**: Nereis has lateral appendages that are referred to as segmental appendages. These appendages are found on each segment of the body. 3. **Analyze the Options**: - **(a) Tentacles**: These are not segmental appendages; they are specific structures that may be present on certain segments but are not repeated on each segment. - **(b) Setae**: These are bristle-like structures that help in locomotion but are not classified as appendages. - **(c) Suckers**: These are used for attachment and are not segmental appendages. - **(d) Parapodia**: These are the correct answer. Parapodia are the lateral appendages found on each segment of Nereis and are involved in swimming and locomotion. 4. **Conclusion**: Based on the analysis, the segmental appendages of Nereis are identified as parapodia. ### Final Answer: The segmental appendages of Nereis are (d) Parapodia. ---
