Hint: It involves microbes and a small quantity of metabolic waste such as bacterially modified bilirubin and dead cells from the digestive system.
Complete answer:
Human excreta refers to human digestive tract waste material and human metabolism, i.e., faeces and urine. It is a toilet layout, wherein human excreta is treated by earthworms. It was examined in India and found to be just an innovative, low-water facility for the healthy treatment of human faeces. Human waste is fully processed into vermi cakes - a resource desperately desired for soil as manure and fertilizers. The eventual use of human excreta as compost in agricultural areas is a chance for people to collect and treat faecal sludge so it can be used to boost soil health. Human excreta is shown to have a strong fertilising ability, providing valuable soil nutrients and also organic compounds that add to building soil quality and reduce soil erosion. Through effective heating, such as composting, all dangerous microbes in human excreta could be destroyed in order to develop fertilisers that become safe to be used in agricultural production.
So, the correct answer is option (A).
Note: Faeces is excreted in a container, as in a plant pot, and sometimes stored in a vessel containing urine as well as other waste. The excrement in the mulch is frequently coated with dirt that may have contributed to the word 'night soil.' In metropolitan areas, a night soil worker appears periodically, at different times, based on the requirement for night soil. Human excrement could be appealing as a fertiliser due to competition for fertiliser and the availability of night soil.
