a. Only 1 and 2
b. Only 2 and 3
c. Only 3
d. None of the above

ANSWER: None of the above
Incinerator and Electrostatic Precipitator are correctly matched. Scrubbers are wet collectors. They remove aerosols from a stream of gas either by collecting wet particles on a surface followed by their removal, or else the particles are wetted by a scrubbing liquid.
