Hydrostatic force is the force that is exerted on a solid object by a body of liquid in static equilibrium. This force is a result of the weight of the liquid pressing down on the object. Option A, Moving water, does not accurately describe hydrostatic force as it is applicable to standing water. Option C, Evaporation of water, does not explain hydrostatic force as it is not related to the pressure exerted by a body of liquid on an object. Option D, Water in the form of ice, is incorrect because hydrostatic force only applies to liquid, not solid, forms of water. Therefore, the correct answer is B, standing water on a solid object.
