The following symbol equation shows aerobic respiration: $\text{C}_6\text{H}_x\text{O}_y + 6\text{O}_2 \rightarrow 6\text{CO}_2 + 6\text{H}_2\text{O}$. Which numbers correspond to the letters shown in the equation as $x$, $y$ and $z$?
- A$x=2, y=12, z=6$
- B$x=6, y=2, z=12$
- C$x=6, y=12, z=2$
- D$x=12, y=6, z=2$
