Answer 1

The correct option is (a) To support combustion

Easy explanation: A large diesel engine plant requires about 0.076 m^3/min to 0.11m^3/min of air per KW of power developed inside the engine. Air contains lot of dust; hence it is necessary to remove the dust content in the atmospheric air.
