Three containers have the same base area $ A $ and are filled with water to the same height $ h $, but they have different shapes: one is cylindrical, one widens toward the top, and one narrows toward the top. Which of the following is true regarding the gauge pressure $ P $ at the bottom and the total force $ F $ exerted by the fluid on the base?

Question

Three containers have the same base area $ A $ and are filled with water to the same height $ h $, but they have different shapes: one is cylindrical, one widens toward the top, and one narrows toward the top. Which of the following is true regarding the gauge pressure $ P $ at the bottom and the total force $ F $ exerted by the fluid on the base?(a) The cylindrical container has the greatest $ F $ because the weight of the water is directly over the base.
, (b) The gauge pressure $ P $ and the force $ F $ are the same for all three containers.
, (c) The widening container has the greatest $ P $ and $ F $ because it holds the most water.
, (d) The narrowing container has the greatest $ P $ because the water is ‘squeezed’ at the bottom.
