By which organ the respiration in frog happens ?

Options

A. Skin
B. Clones
C. Lungs
D. By all the three above

Explanation

**Step-by-Step Solution:**

1. **Understanding the Frog's Respiration**: Frogs are amphibians, which means they can live both on land and in water. This unique characteristic influences how they breathe.

2. **Identifying the Organs Involved**: Frogs have three primary organs that facilitate respiration:
- **Skin**: Frogs have moist skin that allows them to absorb oxygen directly from the environment. This process is known as cutaneous respiration.
- **Mouth**: Frogs can also respire through their mouth. The lining of the mouth can absorb oxygen when the frog opens its mouth and allows air in.
- **Lungs**: Frogs possess lungs, which are used for respiration, especially when they are on land. They inhale and exhale air using their lungs.

3. **Conclusion**: Since frogs utilize all three methods (skin, mouth, and lungs) for respiration, the correct answer to the question is that respiration in frogs happens by all three organs.

**Final Answer**: The respiration in frogs happens by all three organs: skin, mouth, and lungs.
