Solution
The correct option is D B
Biogas is a methane rich fuel gas, produced by the anaerobic breakdown or digestion with the help of methanogenic bacteria.
The given image depicts a biogas plant which is used for the production of biogas. These are mostly situated in rural areas. A biogas plant consists of a 10 -15 feet deep concrete tank known as a digester (D).
It has a charge pit (A) for feeding the slurry of cow dung and water or other organic wastes into the digester where microbes act on the slurry to produce the biogas. A floating gas holder (C) is present over the digester which collects the gas produced within the digester.
There is a pit (B) for collecting the spent slurry which can be used as manure in agricultural fields. Hence option d is correct
