Question

Life cannot originate from inorganic materials at present because of:

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

Answer 1

The correct option is B

A very high amount of oxygen in the atmosphere

The correct option is B:

Explanation of the correct option:

1. Life cannot currently arise from inorganic materials because of the enormous levels of atmospheric oxygen in the environment.
2. It occurs as a result of oxidizing nature of oxygen gas, which oxidizes the inorganic materials in our environment and so becomes an impediment in the chemical origin of life.

Explanation of the incorrect options:

Options A, C, and D:

High pollution, temperature, and absence of raw material are not obstacles in the origination of life from inorganic materials.

Final answer: Life cannot originate from inorganic materials at present because of a very high amount of oxygen in the atmosphere.
