Which is the balanced symbol equation for aerobic respiration?

[1]
A

6CO2+6H2O→C6H12O6+6O26\text{CO}_2 + 6\text{H}_2\text{O} \rightarrow \text{C}_6\text{H}_{12}\text{O}_6 + 6\text{O}_26CO2​+6H2​O→C6​H12​O6​+6O2​

B

C6H12O6+6H2O→6CO2+6O2\text{C}_6\text{H}_{12}\text{O}_6 + 6\text{H}_2\text{O} \rightarrow 6\text{CO}_2 + 6\text{O}_2C6​H12​O6​+6H2​O→6CO2​+6O2​

C

C6H12O6+6O2→6CO2+6H2O\text{C}_6\text{H}_{12}\text{O}_6 + 6\text{O}_2 \rightarrow 6\text{CO}_2 + 6\text{H}_2\text{O}C6​H12​O6​+6O2​→6CO2​+6H2​O

D

6O2+6H2O→C6H12O6+6CO26\text{O}_2 + 6\text{H}_2\text{O} \rightarrow \text{C}_6\text{H}_{12}\text{O}_6 + 6\text{CO}_26O2​+6H2​O→C6​H12​O6​+6CO2​
