Step 1: When a body is just floating on the surface of a liquid, it is in a state of equilibrium. This occurs when the density of the body is equal to the density of the liquid, resulting in a buoyant force that balances the weight of the body.
Step 2: If the body is slightly pushed down, it will displace a greater volume of liquid than before. According to Archimedes' principle, the buoyant force acting on the body increases as it displaces more liquid.
Step 3: As long as the density of the body remains equal to the density of the liquid, the buoyant force will eventually balance the weight of the body once again, pulling it back towards the surface.
Conclusion: Therefore, after being pushed down, the body will slowly come back to its earlier position, making option A the correct answer.
