(b) $CH_4, H_2, NH_3$ and water vapor at $600^{\circ} C$
(c) $CH_3, H_2, NH_3$ and water vapor at $600^{\circ} C$
(d) $CH_4, H_2, NH_3$ and water vapor at $800^{\circ} C$

Answer : d
Hints & Solution
(d) In 1953, S.L. Miller, an American scientist created electric discharge in a closed flask containing $CH_4, H_2, NH_3$ and water vapor at $800^{\circ} C$. The Miller-Urey experiment provided the first evidence that organic molecules needed for life could be formed from inorganic components. Some scientists support the RNA world hypothesis, which suggests that the first life was self-replicating RNA.
