By continuity equation, the area is inversely proportional to velocity so with the increase in area in the diverging section velocity decreases and therefore by Bernoulli's equation we can conclude that the pressure must increase in this region.

Pressure must increase in the divergent portion of venturimeter as the velocity of flow decrease.

Yes, as area increases velocity decreases and pressure should increase.

Why should decrease?
We know that area increase velocity decrease and pressure increase.
We know that area increase velocity decrease and pressure increase.

Through convergent section : kinetic energy will increase and presser energy will decrease.
Through Divergent section : kinetic energy will decrease and pressure energy will increase.
Through Divergent section : kinetic energy will decrease and pressure energy will increase.

The Correct answer is C decrease because P=F/A so as area increase pressure decrease.

The velocity reaches its maximum value and pressure reaches its minimum value at the throat. Subsequently, a decrease in the velocity and an increase in the pressure takes place in course of flow through the divergent part.
