Solution
The correct option is B CH4
The primitive atmosphere of earth was reducing atmosphere with little or no oxygen but was rich in water vapour, carbon monoxide, carbon dioxide, nitrogen and hydrogen. UV light, high temperature and lightening served as sources of energy for chemical reactions between primitive gases to form simple inorganic elements such as water, ammonia, methane and cyanides. These simple elements were washed from atmosphere to ocean through rain wherein polymerization and condensation reactions formed simple organic compounds such as sugars, amino acids, fatty acids, glycerol and nucleotides. It has been experimentally proved that a mixture of methane, water vapour, hydrogen and ammonia can form complex organic compounds. The short hydrocarbon skeleton or long hydrocarbon chains as present in carbohydrates, amino acids, fatty acids and nucleotide bases were provided by methane.Therefore, the correct answer is option B.
