The figure below shows a container filled with water to the height shown. When we compare the pressure at A to the pressure at B, we find that:
A) $p_{A}=\frac{1}{4} p_{B}$ .
B) $p_{A}=\frac{1}{2} p_{B}$ .
C)pA = pB.
D)pA = 2pB.
E)pA = 4pB.

The pressure at any given point in a fluid is solely dependent on the height of the fluid above that point (as long as the fluid is incompressible and at rest). In this case, the height of the water above points A and B are the same, therefore the pressure at A is equal to the pressure at B.
