Both A and R are correct and R is the correct explanation of A.

Biogas typically refers to a mixture of different gases produced by the breakdown of organic matter in the absence of oxygen in biogas plants, which can serve as a source of lighting and cooking gas in rural areas. Biogas can be produced from raw materials such as agricultural waste, manure, municipal waste, plant material, sewage, green waste or food waste etc. In rural areas animal wastes or cowdung is available in large quatities which are degraded in relatively simple biogas plants that are built next to the houses in rural areas.
