Evolution

From his experiments, S.L. Miller produced amino acids by mixing the following in a closed flask:

A. $C H_{4}$ , $H_{2}$ , $N H_{3}$ and water vapour at 800 °C✓
B. $C H_{3}$ , $H_{2}$ , $N H_{4}$ and water vapour at 800 °C
C. $C H_{4}$ , $H_{2}$ , $N H_{3}$ and water vapour at 600 °C
D. $C H_{3}$ , $H_{2}$ , $N H_{3}$ and water vapour at 600 °C

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
