The answer is B.
Divergent portion velocity decrese and pressure increase exit.
Divergent portion inlet velocity increase and pressure decrease.
Divergent portion velocity decrese and pressure increase exit.
Divergent portion inlet velocity increase and pressure decrease.

As we know the pressure is calculated by formula gamma *h, hence h will become less than in convergent portion so the answer is "decreases".

Pressure increases in divergent section that's why length of divergent section is increased so that pressure increases gradually else flow would not happen from low pressure region in throat to high pressure region.

According to Bernoulli equation in divergent portion Area increases, than Kinetic energy decreases, thus pressure energy also increases.
So, exactly Pressure energy increases.
So, exactly Pressure energy increases.

Pressure is increase if velocity decrease.

According to the continuity equation A1V1=A2V2, the velocity is inversely proportional to the cross-section, so the velocity decreases with the increase in the area.
-> Similarly, according to the Bernoulli theorem, the pressure is inversely proportional to the velocity of the moving particles.
Thus, this implies the divergent section of the venturi meter has less velocity with maximum pressure.

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.
