Options

A. High degree of environmental pollution
B. Very high atmospheric temperature
C. A very high amount of oxygen in the atmosphere
D. Absence of raw materials

Explanation

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

1. **Understanding the Question**: The question asks why life cannot originate from inorganic materials at present. We need to analyze the options provided to find the correct reason.

2. **Analyzing the Options**:
- **Option A: High degree of environmental pollution**: Pollution is not a factor that prevents the origin of life. Therefore, this option is incorrect.
- **Option B: Very high atmospheric temperature**: High temperatures can actually promote the formation of life by providing energy. Thus, this option is also incorrect.
- **Option C: A very high amount of oxygen in the atmosphere**: In the primitive Earth, there was no free oxygen present; it was a reducing environment. The presence of high amounts of oxygen today would lead to the oxidation of organic molecules, preventing their accumulation and thus hindering the origin of life. This option is correct.
