Which one of the following is the major constituent of biogas?

Options

  1. ACarbon dioxide
  2. BNitrous oxide
  3. CMethane
  4. DOxygen

Correct answer

C. Methane

Step-by-step solution

Biogas is primarily composed of methane and carbon dioxide ( 45 to 70 % methane 30 to 45 % carbon dioxide.). It also contains trace amounts of nitrogen, hydrogen, and carbon monoxide.
