On what type of pump would you find an impeller?

AI Explanation
The correct answer is B) Centrifugal. A centrifugal pump uses an impeller to create suction and move fluid through the pump. The impeller is a rotating component that pulls the fluid into the center of the pump and flings it outward, generating the necessary pressure to move the fluid. This is the defining characteristic of a centrifugal pump. The other answer choices do not use an impeller. Gear pumps, vane pumps, and piston pumps use different mechanisms to move fluid, such as meshing gears, sliding vanes, or reciprocating pistons, respectively. Only centrifugal pumps rely on an impeller to create the pumping action.
