The mode of respirations in frog that occurs in water is 

Options

A. buccophayngeal, cutaneous & pulmonary
B. buccophayngeal and pulmonary
C. cutaneous only
D. pulmonary only

Answer

### Step-by-Step Solution:

1. **Understanding Frog Respiration**: Frogs have two primary modes of respiration: one that occurs in water and another that occurs on land. It’s important to distinguish between these two modes when answering the question.

2. **Identifying Water Respiration**: The question specifically asks about the mode of respiration that occurs when frogs are in water.

3. **Recognizing the Breathing Organ in Water**: In water, frogs primarily use their skin as the organ for respiration. This process is known as cutaneous respiration.

4. **Defining Cutaneous Respiration**: Cutaneous respiration is the process where oxygen is absorbed through the skin. This method of respiration is effective because the skin of frogs is moist and has a rich supply of blood vessels, allowing for efficient gas exchange.

5. **Conclusion**: Therefore, the mode of respiration in frogs that occurs in water is called **cutaneous respiration**.

### Final Answer:
The mode of respiration in frogs that occurs in water is **cutaneous respiration**.
