Correct option is D
The major component of biogas is methane (CH₄), which typically makes up about 50-75% of biogas. It is a highly combustible gas produced through the anaerobic digestion of organic materials such as food waste, agricultural waste, and manure.
- Methane is the primary constituent of biogas.
- Methane makes up 50-75% of the composition of biogas.
- Biogas is produced through anaerobic digestion by microbes.
- Biogas can be used as a renewable source of energy.
- Other gases in biogas include carbon dioxide (CO₂), which is present in smaller amounts.
- Biogas is a clean and sustainable energy source, reducing dependence on fossil fuels.
- Butane: A gaseous hydrocarbon, not typically a component of biogas.
- Propane: Like butane, propane is a hydrocarbon, not a major component of biogas.
- Ethane: A less common component of biogas, with methane being the dominant gas.
