The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Formation of Earth**: The Earth is believed to have formed approximately 4.5 billion years ago. During this time, the conditions on the planet were vastly different from what we experience today. 2. **Composition of the Primitive Atmosphere**: The primitive atmosphere was composed primarily of gases such as water vapor, carbon dioxide, ammonia, and methane. Notably, it lacked free oxygen (O2). 3. **Nature of the Atmosphere**: Due to the absence of oxygen, the atmosphere of primitive Earth is classified as a "reducing atmosphere." This means that it had a chemical environment that favored the formation of organic compounds, as opposed to an oxidizing atmosphere, which would be more hostile to the formation of such compounds. 4. **Conclusion**: Based on the characteristics of the primitive atmosphere, the correct answer to the question is that the atmosphere of primitive Earth was a reducing atmosphere. **Final Answer**: The atmosphere of primitive Earth was a reducing atmosphere. ---
