• B. Vermicomposting
• C. Biogas production
• D. Landfills

Answer 1

Answer: (B), (C)

The correct options are
B Vermicomposting
C Biogas production

Biogas can be prepared from animal excreta and organic waste from the kitchen. Earthworms eat cow dung along with other farm wastes and pass it through their body and in the process convert it into vermicompost. The municipal wastes; non-toxic solid and liquid waste of the industries and household garbage can also be converted into vermicompost in the same manner.
