Which gas is the major component of biogas?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. Methane.
The major component of biogas is methane (CH₄), which typically constitutes about 50-70% of biogas. Biogas is produced through the anaerobic digestion of organic matter by microorganisms. Along with methane, biogas also contains carbon dioxide (CO₂) and trace amounts of other gases such as hydrogen sulfide (H₂S) and ammonia (NH₃). Methane is the primary component responsible for the energy content and flammability of biogas, making it a valuable source of renewable energy.
