Life cannot originate from inorganic matter in present scenario because of

Options

A. High pollution
B. High atmospheric temerature
C. Oxidising environmnet
D. Absence of raw materials

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks why life cannot originate from inorganic matter in the present scenario.

2. **Reviewing the Options**: The options provided are:
- High pollution
- High atmospheric temperature
- Oxidizing environment
- Absence of raw material

3. **Analyzing Each Option**:
- **High Pollution**: This factor does not directly influence the origin of life from inorganic matter. Therefore, it is not a valid reason.
- **High Atmospheric Temperature**: While high temperatures may have been present during the early Earth, they do not prevent the formation of life today. This option is also incorrect.
- **Oxidizing Environment**: In the present day, the atmosphere contains about 20% oxygen. This high level of oxygen leads to oxidation of inorganic compounds, preventing them from accumulating and forming life. This is a strong reason why life cannot originate from inorganic matter now.
- **Absence of Raw Material**: Raw materials necessary for life are still abundant today. Thus, this option does not explain why life cannot originate from inorganic matter.

4. **Conclusion**: The most valid reason for the inability of life to originate from inorganic matter in the present scenario is the oxidizing environment.

5. **Final Answer**: Life cannot originate from inorganic matter in the present scenario because of the oxidizing environment.
