When the speed and impeller's dia is high then high vacumn create inside the impeller and a good head is develop.

What is meant by head?

Energy divide by its weight is called head. Unit of head is m.

Discharge press is directly proportional to pump head.

This discharge press depends on impeller dia and rpm(velocity).

As the diameter increases, the centrifugal force tends to increase which results in increase in head of a fluid.

Head means the pump discharge the liquid at the maximum height is called head it is dependence on its speed (consider the all friction losses).

Because HEAD is direct proportional speed N.

Head = (impeller blade velocity at outlet/g) [impeller blade velocity at outlet-Q/ (peripheral area of impeller * tanB) ].

Since peripheral area includes a diameter of the impeller so the answer is both A and B therefor option is correct.
