  • A.Generator
  • B.Heater
  • C.Incinerator
  • D.Smelter

Answer: C

A plant for disposing of solid wastes is an incinerator.

An incinerator burns solid waste at high temperature, reducing its volume to ash and gases; it is used especially for hospital and hazardous wastes.

A generator produces electricity, a heater produces heat for warming, and a smelter extracts metal from ore. None is built to dispose of waste.

Incineration reduces waste volume by about 90%, but it must be fitted with pollution controls because burning waste can release dioxins and other harmful gases.
