Answer:
Option a → 4 mol NH₃
Explanation:
This the unbalanced reaction
NH₃  +  O₂  ⟶  N₂  +  H₂O
The balanced reaction:
4NH₃  +  3O₂  →  2N₂  +  6H₂O
4 mol of ammonia
3 mol of oxygen
2 mol of nitrogen
6 mol of water

You might have meant hemiacetal, not hemicetal.
Acetals contain two –OR groups, one –R group and a –H atom. In hemiacetals, one of the –OR groups in acetals is replaced by a –OH group<span>.
