Because discharge(Q) remain constant always through a pipe.

The discharge of steam in CD nozzle INCREASES after throat because pressure energy in convergent part is converted into kinetic energy in divergent part.

Discharge in any pipe flow remains constant only the velocity decrease when area increases.

What is convergent and what is divergent?

Continuity equation self satisfies the statement as mass flow rate of any fluid remains constant throughout any cross section (here it is a nozzle).

P decrease then v increase, so according av = c.
v increase Q discharge increase.

P decrease then v increase, so according av = c.
v increase Q discharge increase. So in divergent portion of nozzle P remain constant.
So Q will be remain content.

How can it possible? I can not understand please describe.

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?

What does discharge mean?

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.
