\nThe correct answer is A. Biogas is produced by the anaerobic digestion of organic matter. Its main constituent is methane ($\\text{CH}_4$).
\n<\/section>\n
\n– Biogas is primarily composed of methane (typically 50-75%) and carbon dioxide ($\\text{CO}_2$) (typically 25-50%).
\n– Methane is the combustible component of biogas, making it valuable as a fuel.
\n<\/section>\n
\nOther gases present in biogas in smaller quantities include hydrogen ($\\text{H}_2$), hydrogen sulphide ($\\text{H}_2\\text{S}$), nitrogen ($\\text{N}_2$), and oxygen ($\\text{O}_2$). The proportion of these gases varies depending on the feedstock and digestion conditions. While carbon dioxide is also a major component by volume, methane is the main constituent that provides the energy when burned.
