(B) scrubber is an air pollution control device that uses a liquid spray to remove particulate matter or gases from an industrial exhaust stream. In industrial processes,scrubbers are primarily used to remove harmful gases like $SO_2$ (Sulphur dioxide) from the exhaust gases before they are released into the atmosphere. The exhaust is passed through a spray of water or lime,which reacts with $SO_2$ to form calcium sulphite or sulphate,thereby preventing it from polluting the air.
