The correct Answer is:
To determine the correct statement from the options provided, we will analyze each statement regarding the excretory products and structures of different organisms. ### Step-by-Step Solution: 1. **Analyzing the first statement**: - **Tetpol larva** excretes ammonia as its waste product. - **Frog** excretes urea as its waste product. - **Conclusion**: The waste products of tetpol larva and frog are different (ammonia vs. urea). This statement is **incorrect**. 2. **Analyzing the second statement**: - **Earthworm** has nephridia as its excretory structure. - **Cockroach** has Malpighian tubules as its excretory structure. - **Conclusion**: The excretory structures of earthworm and cockroach are different (nephridia vs. Malpighian tubules). This statement is **incorrect**. 3. **Analyzing the third statement**: - **Marine fishes** primarily excrete urea. - **Freshwater fishes** primarily excrete ammonia. - **Conclusion**: The waste products of marine and freshwater fishes are different (urea vs. ammonia). This statement is **incorrect**. 4. **Analyzing the fourth statement**: - **Planarian** has flame cells as its excretory structure. - **Amphioxus** (also known as lancelet) has a different structure called proto-nephridia. - **Conclusion**: The excretory structures of planarian and amphioxus are different (flame cells vs. proto-nephridia). This statement is **incorrect**. ### Final Conclusion: All the statements provided are incorrect. Therefore, there is no correct statement among the options given.
