The correct Answer is:
**Step-by-Step Solution:** 1. **Understand the Function of Nephridia in Earthworms:** - Nephridia are excretory organs found in earthworms. Their primary function is to remove waste products from the body and help in osmoregulation. 2. **Identify the Options Given:** - The question provides several options that might serve a similar function to nephridia in other organisms: - Parotid glands in toads - Statocysts in prawns - Flame cells in liver flukes - Myotomes in fish 3. **Analyze Each Option:** - **Parotid Glands in Toads:** - These glands are not excretory organs; they secrete toxins for defense against predators. - **Statocysts in Prawns:** - Statocysts are balancing organs and do not serve an excretory function. - **Flame Cells in Liver Flukes:** - Flame cells are indeed excretory structures that help in osmoregulation and waste removal, functioning similarly to nephridia in earthworms. - **Myotomes in Fish:** - Myotomes are muscle segments that aid in movement, not in excretion. 4. **Conclusion:** - The correct answer is **flame cells in liver flukes**, as they serve a similar excretory function as nephridia in earthworms. **Final Answer:** Flame cells in liver flukes. ---
