Which of the following was not used by Stanley L .Miller and Harold C. Urey while creating a primitive environment in the laboratory?

Yes, it is the correct answer. Stanley L. Miller and Harold C. Urey conducted the Miller-Urey experiment in 1953 to demonstrate how  life would have originated on the earth. They created an environment in laboratory, which mimicked the environment of earth as it was during the time of origin of life. Water, methane, ammonia and hydrogen were used in that experiment.
