Answer: (A), (B), (C), (D)

The major disadvantage of biogas is its contribution in emitting greenhouse gases. Other than that, biogas has many advantages. It is cost effective, easy to operate. Biogas can replace your regular LPG cylinder in cooking. It can also be used for lighting your homes. And the organic matter that remains can be used as a manure in farming.
