Best answer
Correct choice is (a) Impeller

The explanation is: An impeller is a rotating component of a centrifugal pump which transfers energy from the motor that drives the pump to the fluid being pumped by accelerating the fluid outwards from the center of rotation. This is how mixing is accomplished.
