Which equation gives the correct balanced equation for the complete combustion of a hydrocarbon with formula $\text{C}_x\text{H}_y$?
- A$\text{C}_x\text{H}_y + \left(x + \frac{y}{2}\right)\text{O}_2 \rightarrow x\text{CO}_2 + \frac{y}{2}\text{H}_2\text{O}$
- B$\text{C}_x\text{H}_y + \left(x + \frac{y}{4}\right)\text{O}_2 \rightarrow x\text{CO}_2 + y\text{H}_2\text{O}$
- C$\text{C}_x\text{H}_y + \left(x + \frac{y}{4}\right)\text{O}_2 \rightarrow x\text{CO}_2 + \frac{y}{4}\text{H}_2\text{O}$
- D$\text{C}_x\text{H}_y + \left(x + \frac{y}{4}\right)\text{O}_2 \rightarrow x\text{CO}_2 + \frac{y}{2}\text{H}_2\text{O}$
