Which of the following is a centrifugal pump part?

Explanation:
Centrifugal pumps rely on an impeller spinning inside a volute to move fluid. The volute is the housing that surrounds the impeller and collects the high-velocity fluid, then expands to convert that velocity into pressure so the fluid exits the pump efficiently. The other items fit different pump concepts: a diaphragm is used in diaphragm pumps, a piston is typical of positive-displacement piston pumps, and a rotor is usually part of a motor or a different kind of rotating component, not a specific centrifugal-pump part. So the volute is the component that identifies a centrifugal pump.
