Answer
$\mathrm{A}=\mathrm{B}=\mathrm{C}=\mathrm{D}$
Work Step by Step
If the pressure at one point in a fluid is $\mathrm{P}_{1}$, the pressure at a depth $\mathrm{h}$ below that point is
$\mathrm{P}_{2}=\mathrm{P}_{1}+\rho \mathrm{g}\mathrm{h} \qquad $15-7
---
At depth h,
$\Delta P=\rho gh$ for each container.
The pressures are the same for all four containers.
