Which equation represents the incomplete combustion of methane?

[1]
A

CH4+2O2→CO2+2H2O\text{CH}_4 + 2\text{O}_2 \rightarrow \text{CO}_2 + 2\text{H}_2\text{O}CH4​+2O2​→CO2​+2H2​O

B

2CH4+3O2→2CO+4H2O2\text{CH}_4 + 3\text{O}_2 \rightarrow 2\text{CO} + 4\text{H}_2\text{O}2CH4​+3O2​→2CO+4H2​O

C

CH4+O2→CO2+2H2\text{CH}_4 + \text{O}_2 \rightarrow \text{CO}_2 + 2\text{H}_2CH4​+O2​→CO2​+2H2​

D

2CH4+4O2→2CO2+4H2O2\text{CH}_4 + 4\text{O}_2 \rightarrow 2\text{CO}_2 + 4\text{H}_2\text{O}2CH4​+4O2​→2CO2​+4H2​O
