In the larva of frog the respiration is carried out by

Options

A. gills
B. lungs
C. skin
D. skin and gills.

Answer

### Step-by-Step Solution:

1. **Identify the Larval Stage of Frogs**: The larva of frogs is known as a tadpole. Understanding that the question pertains to this specific stage is crucial.

2. **Understand the Habitat of Tadpoles**: Tadpoles are aquatic organisms, meaning they live in water. This is important because the mode of respiration often depends on the environment.

3. **Consider the Respiratory Structures Available**: In general, organisms that live in water typically have gills for respiration. Since tadpoles are aquatic, they are expected to utilize gills.

4. **Evaluate the Other Options**:
- **Lungs**: Tadpoles do not possess lungs as they are not yet developed into adult frogs.
- **Skin**: While skin can serve as a respiratory surface (cutaneous respiration), it is not the primary means of respiration for tadpoles.
- **Skin and Gills**: This option suggests that both structures are used for respiration.

5. **Conclusion**: Since tadpoles primarily use gills for respiration, but also have the ability to perform cutaneous respiration through their skin, the most accurate answer is that respiration in the larva of frogs (tadpoles) is carried out by both gills and skin.

### Final Answer:
In the larva of frogs (tadpoles), respiration is carried out by **gills and skin**.
