Water flows through a frictionless duct with a cross-section varying a...
When the cross section of duct decreases the velocity of water increases and in accordance with Bernoulli's theorem the pressure decreases at that place.
Therefore, in this case, the pressure remains constant initially and then decreases as the area of cross section decreases along the neck of the tube and then remains constant along the mouth of the tube.
Hence, the graph in option A is correct.

Option A is the correct answer.
Exp: When the area of the pipe decreases then velocity increases and pressure decreases.
