Final answer:
The pressure of the fluid in different regions can be ranked from lowest to highest as follows: Region A, Region B, Region C, Region D (highest pressure).
Step-by-step explanation:
The pressure of a fluid depends on the depth from the surface and not on the shape of the container. In this scenario, the fluid is in different regions, so we can rank the pressure from lowest to highest as follows:
- Region A
- Region B
- Region C
- Region D (highest pressure)
Region D has the highest pressure because it is at the greatest depth, while Region A has the lowest pressure because it is at the surface.
