Because its cross section area of tube gradually decreases from entrance to the throat. Venturimeter is a good example of convergent nozzle.

Nozzles are 3 types:
1) Convergent type.
2) Divergent type.
3) Convergent-Divergent type.
1) Convergent type.
2) Divergent type.
3) Convergent-Divergent type.

When exit area of nozzle decrease then velocity energy increase.

When area decrease pressure will also decrease, but velocity will increase.

When area decreases pressure will decreases, then fluid velocity become increses.

When area increase than pressure decrease.

I disagree with a @Salman statement because decrease in cross section will increases the pressure and velocity also increases.

Convergent as name implies decrease in size mainly by cross section So, Answer is B. This shape is mainly used to decrease pressure and conversely increasing velocity.
