Archimedes principle states that when a body is immersed wholly or partially in a liquid, it experiences an upward buoyant force of magnitude equal to the weight of the liquid displaced by it.
Buoyant force = Weight of displaced liquid
Weight of displaced liquid = Mass of the displaced liquid × Acceleration due to gravity
= Density of the liquid × Volume of the displaced liquid × Acceleration due to gravity
∴Volume of the displaced liquid = Volume of the object that is immersed in the liquid
∴Weight of the displaced liquid = Volume of the object immersed in the liquid × Density of the liquid × Acceleration due to gravity
So, this rules out options B, C and D. The only option left is A - Weight of the body
