Show answer & explanation

Correct answer: D

Waste-to-energy incineration serves a dual purpose: disposing of municipal solid waste and generating energy. The process produces both bottom ash (from the furnace) and fly ash (captured from flue gases). Additionally, environmental concerns include the generation of high-level toxic air pollutants like dioxins and the presence of toxic metals such as lead and mercury in the residues. Since statements A, B, C, D, and E are all factually correct regarding this process, the correct choice is Option 3.
