Correct Answer: Vermicomposting
Solution : The correct answer is Vermicomposting.
Vermicomposting is a scientific process of producing compost in which organic waste is converted into highly nutritious manure by earthworms. Earthworms feed on organic waste and produce "vermicasts", which are rich in minerals, including calcium, magnesium, potassium, phosphorus, as well as nitrates. These improve the quality of the soil and are used as fertilisers.
