Solution
The correct option is D A. J. Oparin
According to Oparin, the conditions that prevailed on primitive earth about 4 million years ago were ideal for chemical evolution. The primitive atmosphere of earth was reducing atmosphere that lacks molecular oxygen but was rich in water vapour, carbon monoxide, carbon dioxide, nitrogen and hydrogen. The absence of oxygen allowed the formed peptides to remain unspoiled and facilitated further chemical reactions to produce more complex protein structures. The high temperature, UV light and lightening served as an energy source for the polymerization of amino acids. The absence of living organisms prevented degradation of peptides by microbes. So, the correct answer is option D.
