D. Its yong one, tadpole, is aquatic in its habitat

Answer

### Step-by-Step Solution:

1. **Definition of Amphibians**: Amphibians are a class of animals that can live both in water and on land. This dual habitat is a key characteristic that defines them.

2. **Characteristics of Frogs**: Frogs, as amphibians, exhibit specific traits that align with the definition of amphibians. They have moist skin, which is essential for respiration and hydration.

3. **Life Cycle of Frogs**: The life cycle of a frog includes an aquatic larval stage (tadpole) and a terrestrial adult stage. The tadpoles live in water and breathe through gills, while adult frogs primarily breathe through lungs and their skin.

4. **Respiration**: Adult frogs have lungs for breathing air, but they can also absorb oxygen through their moist skin. This dual method of respiration is common among amphibians.

5. **Conclusion**: Frogs are classified as amphibians primarily because they can live in both aquatic and terrestrial environments, which is a unique characteristic that distinguishes them from other animal groups.

### Final Answer:
Frog is called an amphibian because it can live in both land and water.
