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

1. A
   \( \text{CH}_3, \text{H}_2, \text{NH}_4 \) and water vapour at \( 80^\circ\text{C} \)
2. B
   \( \text{CH}_4, \text{H}_2, \text{NH}_3 \) and water vapour at \( 600^\circ\text{C} \)
3. C
   \( \text{CH}_3, \text{H}_2, \text{NH}_3 \) and water vapour at \( 600^\circ\text{C} \)
4. D
   \( \text{CH}_4, \text{H}_2, \text{NH}_3 \) and water vapour at \( 800^\circ\text{C} \)
