Life cannot originate from inorganic materials at present because of

1. a very high amount of oxygen in the atmosphere
2. very low atmospheric temperature
3. absence of raw materials
4. high degree of environmental pollution

Correct answer: a very high amount of oxygen in the atmosphere

Solution

A high oxygen atmosphere is strongly oxidizing, so it breaks down or prevents the accumulation of the reduced organic molecules needed for abiotic life formation. Early Earth’s low-oxygen conditions were more favorable for such chemical evolution.
