The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Question**: The question asks about the nature of gill slits in Chondrichthyes, a class of fish that includes sharks and rays. 2. **Identifying the Options**: The options provided are: - A) Uncovered - B) Covered by operculum - C) Absent - D) Only sometimes covered 3. **Classifying Chondrichthyes**: Chondrichthyes are characterized by their cartilaginous skeletons. They are one of the two main classes of fish, the other being Osteichthyes (bony fish). 4. **Analyzing Gill Slits in Chondrichthyes**: - In Chondrichthyes, gill slits are typically found on the sides of the body. - Unlike Osteichthyes, which have gill covers (operculum) that protect their gills, Chondrichthyes do not have this feature. 5. **Conclusion**: Based on the characteristics of Chondrichthyes, the gill slits are generally uncovered. Therefore, the correct answer is option A) Uncovered. **Final Answer**: Gill slits in Chondrichthyes are uncovered. ---
