Answer:
correct option A
The pressure at the base of each vessel is given by ρgh where ρ is a density of water, g is acceleration due to gravity, and h is the height of water column in that vessel.
So pressure at a base is directly proportional to the height of water level.
So decreasing order of pressure is D>B>A>C
