Hydrazine is a gas with molecular formula $\text{N}_2\text{H}_4$. When hydrazine burns in air, nitrogen gas and steam are formed. $\text{N}_2\text{H}_4(g) + \text{O}_2(g) \rightarrow \text{N}_2(g) + 2\text{H}_2\text{O}(g)$. Which statements are correct?
- A1, 2 and 3
- B1 and 2 only
- C2, 3 and 4
- D3 and 4 only
