Verified Answer
Life cannot originate from inorganicmaterials at present because : ...
Oxidising atmosphere is the region that life cannot originate from inorganic materials at present. Today's atmosphere is not conducive to the spontaneous synthesis of complex molecules because the oxygen attacks chemical bonds, extracting electrons. Hence, the correct option is b.

Life cannot originate from inorganicmaterials at present because : ...
The primitive atmosphere of earth was reducing atmosphere with little or no oxygen. Now owing to presence of oxygen, the organic and inorganic compounds are oxidized as soon as they are formed. Origin of life requires accumulation of these compounds followed by their organization into a living cell. This makes option B correct.

Life cannot originate from inorganicmaterials at present because : ...
Answer:
Introduction:
Life is a complex phenomenon that involves the interaction of various organic molecules to form cellular structures. While scientists have been able to create simple organic molecules in the laboratory, the origin of life remains a mystery. One of the biggest challenges in understanding the origin of life is the question of how organic molecules could have formed from inorganic materials.
Explanation:
The answer to this question is option B, "A very high amount of oxygen in the atmosphere." The reason for this is that oxygen is a highly reactive gas that tends to break down complex organic molecules. This process is known as oxidation, and it can occur spontaneously in the presence of oxygen.
The presence of oxygen in the atmosphere is thought to be a relatively recent event in Earth's history. For much of the planet's early history, the atmosphere was composed primarily of carbon dioxide, nitrogen, and other gases. It was only after the evolution of photosynthetic organisms that oxygen began to accumulate in the atmosphere.
Conclusion:
Thus, the presence of oxygen in the atmosphere would have made it difficult for complex organic molecules to form and persist. This is why scientists believe that the origin of life must have occurred in an environment that was free of oxygen. While the question of how life originated remains a mystery, scientists continue to study the conditions that could have supported the formation of organic molecules and the evolution of life on Earth.
