Detailed explanation-1: -In 1953, Stanley Miller and Harold Urey did an experiment to test Oparin and Haldane’s ideas. They found that organic molecules could be spontaneously produced under reducing conditions thought to resemble those of early Earth.
Detailed explanation-2: -In the 1950’s, biochemists Stanley Miller and Harold Urey conducted an experiment which demonstrated that several organic compounds could be formed spontaneously (through abiogenesis) by simulating the conditions of Earth’s early atmosphere.
Detailed explanation-3: -The Miller–Urey experiment (or Miller experiment) is a famous chemistry experiment that simulated the conditions thought at the time (1952) to be present in the atmosphere of the early, prebiotic Earth, in order to test the hypothesis of the chemical origin of life under those conditions.
Detailed explanation-4: -So, the correct answer is ‘Ammonia, methane, hydrogen and water vapour’.
