(D) In $1953$,Stanley Miller and Harold Urey conducted an experiment to test the Oparin-Haldane hypothesis regarding the origin of life. They created a closed system containing $CH_4, NH_3, H_2$ and water vapor $(H_2O)$ in a ratio of $2:1:2$. They subjected this mixture to electric discharges at $800^{\circ}C$ to simulate the conditions of the primitive Earth's atmosphere. After a week,they observed the formation of complex organic molecules,specifically amino acids like glycine,alanine,and aspartic acid,which are the building blocks of proteins.
