Respiration in adult frog is

Options

A. Cutaneous
B. Buccal
C. Pulmonary
D. All the above

Answer

To answer the question "Respiration in adult frog is," we need to analyze the different modes of respiration that frogs utilize. Here’s a step-by-step solution:

### Step 1: Understand the Types of Respiration
Frogs, being amphibians, can respire in multiple ways. The three primary types of respiration in adult frogs are:
1. **Cutaneous Respiration**: This is respiration through the skin. Frogs have moist skin that allows for the exchange of gases directly with the environment.
2. **Buccal Respiration**: This occurs through the lining of the buccopharyngeal cavity. Frogs can take in air through their mouth and push it into their lungs.
3. **Pulmonary Respiration**: This involves the use of lungs. Frogs primarily use their lungs when there is a high demand for oxygen, such as during vigorous activity.

### Step 2: Analyze the Options
The question provides four options:
1. Cutaneous
2. Buccal
3. Pulmonary
4. All of the above

Since we have established that frogs can utilize all three types of respiration, we can conclude that the correct answer must include all of them.

### Step 3: Conclusion
Given that adult frogs can respire through their skin (cutaneous), through their buccopharyngeal cavity (buccal), and through their lungs (pulmonary), the correct answer to the question is:
**All of the above.**
