C Correct answer
Explanation

Archimedes discovered the principle of buoyancy around 250 BC when he noticed water displacement while bathing, leading to his famous 'Eureka' moment. The principle states that a body immersed in fluid experiences an upward force equal to the weight of displaced fluid. This explains why ships float and balloons rise in air.
