Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks which organism respires through gills. Gills are specialized organs used for breathing in aquatic organisms.

2. **Analyzing the Options**:
- **Option 1: Crocodile**: Crocodiles are reptiles that primarily respire through lungs. Therefore, this option is incorrect.
- **Option 2: Vaheel**: The Vaheel is an aquatic mammal. Mammals, including aquatic ones, breathe using lungs. Thus, this option is also incorrect.
- **Option 3: Frog**: Frogs are amphibians. While adult frogs primarily breathe through lungs and their skin, the larval stage (tadpole) does have gills. However, since the question refers to frogs in general, this option is not correct.
- **Option 4: Prawn**: Prawns are small aquatic crustaceans that respire through gills. This option is correct.
