C. CH₄+2O₂ →2H₂O+CO₂

Explanation:

This is a popular combustion reaction.

C. CH₄+2O₂ →2H₂O+CO₂

In combustion, hydrocarbons burn in the presence of oxygen gas and they produce water and carbon dioxide only. The process is accompanied with the release of energy.

We simply say for the above reaction that:

One molecule of methane (CH₄) reacts with two molecules of oxygen gas (O₂) to produce two molecules of water (H₂O) and one molecule of carbon dioxide only
