What method could be used to find the bond energy for the covalent bond X-Y by dividing its $\Delta H$ by $n$?
- A$\text{XY}_n(g) \rightarrow \text{X}(g) + n\text{Y}(g)$
- B$2\text{XY}_n(g) \rightarrow 2\text{XY}_{n-1}(g) + \text{Y}_2(g)$
- C$\text{Y}(g) + \text{XY}_{n-1}(g) \rightarrow \text{XY}_n(g)$
- D$n\text{XY}(g) \rightarrow n\text{X}(g) + \frac{n}{2}\text{Y}_2(g)$
