The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Flame Cells**: Flame cells are specialized excretory cells found in flatworms. They play a crucial role in the excretory system of these organisms. 2. **Function of Flame Cells**: The primary function of flame cells is to remove waste materials from the body of flatworms. They act similarly to kidneys in higher animals, filtering out waste products. 3. **Osmoregulation**: In addition to excretion, flame cells also help in osmoregulation. They maintain the osmotic balance and ionic concentration within the flatworm's body, which is essential for survival, especially in freshwater environments. 4. **Analyzing the Options**: - (i) Osmoregulation: Correct, as flame cells help maintain osmotic balance. - (ii) Digestion: Incorrect, flame cells do not play a role in digestion. - (iii) Reproduction: Incorrect, flame cells are not involved in reproduction. - (iv) Excretion: Correct, as flame cells are responsible for excreting waste. - (v) Bioluminescence: Incorrect, flame cells do not have a role in bioluminescence. 5. **Conclusion**: Based on the functions of flame cells, the correct answers are (i) Osmoregulation and (iv) Excretion. Therefore, the flame cells of flatworms help in both osmoregulation and excretion. **Final Answer**: (i) Osmoregulation and (iv) Excretion. ---
