Answer»

Right choice is (a) Axial FLOW

Easy explanation: An axial flow PUMP is a type of centrifugal pump that uses an IMPELLER with vanes that direct the flow axially. Axial flow pumps create LESS pressure as compared to radial flow centrifugal pumps, but they can produce much higher flow RATES.
