\nThe correct option is B) Methane and carbon dioxide.
\n<\/section>\n
\nBiogas is produced through the anaerobic digestion of organic matter by microorganisms. Its primary constituents are methane (CH\u2084), typically making up 50-75% of the volume, and carbon dioxide (CO\u2082), making up 25-50%. Methane is the main combustible component that gives biogas its value as a fuel.
\n<\/section>\n
\nOther gases present in biogas in smaller quantities may include hydrogen sulfide (H\u2082S), nitrogen (N\u2082), and hydrogen (H\u2082). Sulphur dioxide and nitric oxide are not typical main constituents of biogas; they are more associated with combustion processes or air pollution.
