Answer 1

The correct option is B Using them for producing biogas

Animal or human excreta and organic wastes from kitchen can be most profitably minimized by using them for producing biogas. These wastes release methane and other gases as a result of anaerobic microorganisms. Biogas contains methane in bulk and other gases like CO₂, H₂, N₂ and O₂.Pesticides are the agrochemicals used to kill the pests which reduces crop productivity and antibiotic drugs are made from living organisms such as fungi, molds, and certain soil bacteria that are harmful to disease-causing bacteria.
