D. Water

Answer

**Step-by-Step Text Solution:**

1. **Understanding the Question**: The question asks where life originated. The options provided are air, soil, mountains, and water.

2. **Analyzing the Options**:
- **Air**: While air is essential for many life forms, it is not considered the origin of life.
- **Soil**: Soil supports life but is not the initial source of life.
- **Mountains**: Mountains are geographical features and do not directly relate to the origin of life.
- **Water**: Water is crucial for life and is often considered the environment where life began.

3. **Referencing Scientific Theories**: According to the Oparin theory (a chemical evolution theory), life originated in a primordial "ocean soup." This theory suggests that the early Earth had a hot, dilute mixture of organic compounds in water, which facilitated the formation of simple life forms.

4. **Conclusion**: Based on the Oparin theory and the importance of water in the development of early life forms, we conclude that life originated in water.

5. **Final Answer**: Therefore, the correct answer is option 4: Water.
