To determine which ball requires the strongest force to lift, we need to consider the mass of each ball. The force required to lift an object is usually proportional to its weight, which is dependent on its mass.
Based on the provided options, the soccer ball is stated to require the strongest force to lift because it has the most mass. Since mass directly influences the force of gravity acting on an object, this reasoning is correct.
So the correct response is:
The soccer ball requires the strongest force to lift because it has the most mass.
