The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Chromosome Structure**: Chromosomes are structures within cells that contain DNA. They can take on various shapes during different phases of cell division. 2. **Identifying Meiosis Stages**: Meiosis consists of several stages, particularly during prophase, which is divided into five substages: leptotene, zygotene, pachytene, diplotene, and diakinesis. 3. **Focusing on the Diplotene Stage**: The question specifically asks about the appearance of chromosomes in a ring-like structure. This is observed during the diplotene stage of prophase I of meiosis. 4. **Characteristics of the Diplotene Stage**: During diplotene, homologous chromosomes begin to separate but remain connected at points called chiasmata, where genetic recombination occurs. This separation can give the chromosomes a ring-like appearance. 5. **Conclusion**: Based on the characteristics of the diplotene stage, we conclude that the chromosomes appear ring-like during this phase. Therefore, the correct answer is diplotene. **Final Answer**: Chromosomes are ring-like in the diplotene stage of meiosis. ---
