Correct Answer: Option D
Detailed Explanation:
Biogas is produced by anaerobic digestion of organic matter and contains 50–70% methane (CH₄), which is its primary combustible component.
Propane, butane, and ethane are constituents of petroleum gas and natural gas, not biogas.
Therefore, methane is the main constituent of biogas, making Option 4 the correct answer.
