C Correct answer
Explanation

In vermicomposting toilets (not 'vermin processing'), human excreta is converted into nutrient-rich vermicompost through the action of earthworms. The earthworms break down the organic matter, producing a safe, odorless material that can be used as fertilizer. The process uses natural biological decomposition rather than chemical or energy-intensive treatment.
