The only varying parameters are area and velocity assuming density as constant for sub sonic flow. Discharge is always constant for entire nozzle.

C is the answer. Because the discharge is not constant as area varies from convergent section to throat and throat to divergent section also velocity is different therefore Q = A * V.
A and V varies so Q also varies it us not constant.
To have higher velocity and discharge we use C-D nozzle.
In convergent nozzle, we have a constraint for above two factor.

What if flow is compressible?

Discharge is always remaining constant after the throat that means in divergent portion of the nozzle.

Q = V1A1 = V2A2 is flow rate thus Q is constant.

Mass flow is always constant and m = area * velocity /specific volume.
Q = area * velocity.
Q = area * velocity.
