What is the main result of the combustion process?

The combustion process primarily results in the release of carbon dioxide. During combustion, organic materials, such as fossil fuels or biomass, react with oxygen, producing energy in the form of heat and light, as well as byproducts including water vapor and carbon dioxide. This conversion of energy occurs as carbon-containing substances oxidize, leading to the formation of carbon dioxide, which is a significant greenhouse gas contributing to climate change.

In this context, the other options do not capture the essence of combustion. While the absorption of atmospheric oxygen is a part of the process, it is not the main result; rather, it is necessary for combustion to occur. The creation of food for plants is unrelated, as combustion consumes materials rather than creating new biological matter. Similarly, combustion, by definition, typically produces emissions, so the idea of producing energy without emissions contradicts the fundamental outcome of the combustion process.
