Solution

The correct option is C $C H_{4}, N H_{3}, H_{2}, H_{2} O$

The Miller and Urey experiment were a chemical experiment that demonstrates the origin of life in the primitive condition of the earth.
The experiment used water ( $H_{2} O$ ), methane ( $C H_{4}$ ), ammonia ( $N H_{3}$ ), and hydrogen ( $H_{2}$ ). The chemicals were all sealed inside a sterile $5 - l i t e r$ glass flask connected to a $500 m l$ flask half-full of liquid water. The liquid water in the smaller flask was heated to induce evaporation and the water vapour was allowed to enter the larger flask. Continuous electrical sparks were fired between the electrodes to simulate lightning in the water vapour and gaseous mixture and chemical reaction occur which produces amino acids such as glycine and alanine, a monomer of protein. Thus, the correct answer is option E.
