ANSWER

Biogas is an alternate source of energy produced by the breakdown of organic matter in the absence of oxygen. Biogas can be produced from raw materials such as agricultural waste, manure, municipal waste, plant material, sewage, green waste or food waste. Biogas can be produced by anaerobic digestion with anaerobic bacteria, which digest material inside a closed system, or fermentation of biodegradable materials. Biogas or gobar gas is usually 50% to 80% methane and 20% to 50% carbon dioxide, with traces of gasses such as hydrogen, carbon monoxide, and nitrogen.

Thus, the correct answer is option D.
