Which type of respiration occurs in frog if it is (i) on land or (ii) in water?

Explanation

### Step-by-Step Solution:

2. **Respiration on Land**:

- **Buccopharyngeal Respiration**: This type involves the buccal cavity (mouth) and pharynx. Frogs can absorb oxygen through the lining of their mouth and throat.
