Fluid Statics

In fluid statics, the buoyant force is the force exerted on a submerged or floating body due to the pressure difference in the fluid. The line of action of the buoyant force always passes through the centroid of the displaced fluid. This is a fundamental principle known as Archimedes' principle.
Step 1: Understanding Buoyant Force
According to Archimedes' principle, the buoyant force is equal to the weight of the displaced fluid, and it acts vertically upward. The force's line of action passes through the centroid of the displaced fluid. Therefore, the correct answer is (C).
