\nThe correct answer is (B) Methane.
\n<\/section>\n
\nBiogas is produced from the anaerobic digestion of organic matter. Its primary components are methane (CH4) and carbon dioxide (CO2). Methane is the main combustible component and typically constitutes the largest proportion of biogas, usually ranging from 50% to 75%. Carbon dioxide is the second largest component, making up 25% to 50%.
\n<\/section>\n
\nMinor components of biogas can include hydrogen (H2), hydrogen sulphide (H2S), nitrogen (N2), oxygen (O2), and water vapour. While hydrogen and hydrogen sulphide are present, their concentrations are much lower than methane and carbon dioxide.
