Solution

The correct option is A $W < F_{B}$
Explanation: when the weight of a body is less than the weight of the liquid displaced by it the body will float partially above and partially below the surface of the liquid. In this case the weight of the plastic ball is less than the weight of water so only that much portion of the ball will get submerged in the water by which the weight of the displaced water becomes equal to the weight of the ball.
