Which principle in Classical Mechanics states that a body submerged in a fluid experiences an upward buoyant force equal to the weight of the fluid it displaces?
A. Pascal's Principle
B. Bernoulli's Principle
C. Archimedes' Principle
D. Torricelli's Principle
Archimedes' Principle describes the buoyant force acting on a submerged body, making option C correct.
