The two dams are identical with the exception that the water reservoir behind dam \( \mathrm{A} \) extends twice the horizontal distance behind it as that of dam B. Which one of the following statements regarding these two dams is correct?
(A) The force exerted by the water on dam \( \mathrm{A} \) is greater than that on dam B.
(B) The force exerted by the water on dam B is greater than that on dam A.
(C) Dam A is more likely to collapse than dam B if the water level rises.
(D) The horizontal distance of the water behind the two dams does not determine the force on them.
