Gobar gas mainly contains A. Carbon dioxide B. Carbon monoxide C. Hydrogen sulphide D. Methane

Carbon dioxide
Carbon monoxide
Hydrogen sulphide
Methane

The correct answer is D. Methane.

Gobar gas is a type of biogas that is produced by the anaerobic decomposition of animal manure. It is a renewable energy source that can be used for cooking, heating, and lighting. Gobar gas is a mixture of

gases, including methane, carbon dioxide, hydrogen, and nitrogen. Methane is the main component of gobar gas, making up about 50-70% of the gas. Carbon dioxide makes up about 20-30% of the gas, and hydrogen and nitrogen make up the remaining 10-20%.

Gobar gas is a clean-burning fuel that produces fewer emissions than traditional fuels such as coal and oil. It is also a renewable resource that can be produced on a small scale, making it a good option for rural communities.

The other options are incorrect because they are not the main components of gobar gas. Carbon dioxide is a greenhouse gas that contributes to climate change. Hydrogen sulphide is a toxic gas that can cause respiratory problems.
