Answers (1)

Answer : (A)

Biogas is a renewable energy source composed of methane, carbon dioxide, and other trace compounds produced from anaerobic digestion of organic matter.

Bio gas composition:

Methane CH4                       55%-75%

Carbon dioxide CO2             25% - 40%

Rest are trace gases like hydrogen etc.

Biogas is predominantly made from the excretion of cows and buffalos. This is the reason they produce a lot of methane gas.
