The correct answer is A,
q = d.
h =d^2.
p = d^3.
q = d.
h =d^2.
p = d^3.

Q = A.V.
A = π/4D2.
Q is directly proportional to d2.
A = π/4D2.
Q is directly proportional to d2.

The Answer is B.
Discharge of centrifugal pump is directly proportional to its (dia)^2.
Q = A * V,
Here A = π * D^2/4.
Discharge of centrifugal pump is directly proportional to its (dia)^2.
Q = A * V,
Here A = π * D^2/4.

Q/(N*D^3).
So, the correct answer is directly proportional to D^3.
So, the correct answer is directly proportional to D^3.
