Best answer
Right option is (c) Cyclone separator

Easiest explanation: Cyclones are mostly used for removing industrial dust from air or process gases. They are the principal type of gas-solid separator. The particulate is made to spin rapidly, heavier particle settle down and all the dust is removed out from the ducts. To also remove dust from the pulverized coal cyclone separator are used.
