D Correct answer
Explanation

Archimedes' principle states that an object immersed in a fluid experiences an upward buoyant force equal to the weight of the fluid it displaces. A balloon rises because the gas inside is less dense than the surrounding air, creating a buoyant force greater than its weight.
