AI Generated Solution

The correct Answer is:
### Step-by-Step Solution: 1. **Understanding the Statement**: The statement claims that fishes respire through their skin. This needs to be evaluated for its correctness. 2. **Identifying the Correct Respiratory Organs**: Fishes primarily respire through gills, not skin. Gills are specialized organs that allow for the exchange of gases. 3. **Function of Gills**: Gills are equipped with numerous blood vessels, which facilitate the absorption of oxygen from water and the release of carbon dioxide. 4. **Mechanism of Breathing in Fishes**: - Fishes take in water through their mouths. - The water is then forced over the gills. - As water passes over the gills, oxygen is absorbed into the bloodstream, while carbon dioxide is expelled into the water. 5. **Conclusion**: The initial statement is incorrect. Fishes do not respire through their skin; they respire through their gills, which are specifically adapted for gas exchange in an aquatic environment.
