What is the correct balanced equation for the combustion of octane, C8H18\text{C}_8\text{H}_{18}C8​H18​?

C8H18+17O2→8CO2+9H2O\text{C}_8\text{H}_{18} + 17\text{O}_2 \rightarrow 8\text{CO}_2 + 9\text{H}_2\text{O}C8​H18​+17O2​→8CO2​+9H2​O

C8H18+8O2→8CO2+9H2O\text{C}_8\text{H}_{18} + 8\text{O}_2 \rightarrow 8\text{CO}_2 + 9\text{H}_2\text{O}C8​H18​+8O2​→8CO2​+9H2​O

2C8H18+25O2→16CO2+18H2O2\text{C}_8\text{H}_{18} + 25\text{O}_2 \rightarrow 16\text{CO}_2 + 18\text{H}_2\text{O}2C8​H18​+25O2​→16CO2​+18H2​O

2C8H18+34O2→16CO2+18H2O2\text{C}_8\text{H}_{18} + 34\text{O}_2 \rightarrow 16\text{CO}_2 + 18\text{H}_2\text{O}2C8​H18​+34O2​→16CO2​+18H2​O
