The figure shows a horizontal pipe with sections with different cross-sectional areas. Small tubes extend from the top of each section. The cross-sectional area of the pipe at location C is half that at A, and the areas at A and D are the same. Water flows in the pipe from left to right. Which of the following correctly ranks the height $ h $ of the water in the tubes above the labeled locations?

Question

The figure shows a horizontal pipe with sections with different cross-sectional areas. Small tubes extend from the top of each section. The cross-sectional area of the pipe at location C is half that at A, and the areas at A and D are the same. Water flows in the pipe from left to right. Which of the following correctly ranks the height $ h $ of the water in the tubes above the labeled locations?(a) $ h_A = h_B = h_C = h_D $
, (b) $ h_A > h_B > h_C > h_D $
, (c) $ (h_A = h_D) > h_B > h_C $
, (d) $ h_C > h_B > (h_A = h_D) $
