If a body submerged in water were placed on a spring scale at the bottom of the water, the scale would indicate the upward force of the object that has the same magnitude as mg-E, therefore, submerged objects appear to weigh less than they normally weigh. Which of the following statements is true?

I - The buoyancy force is equal to the weight of the fluid displaced by the submerged part of a floating object.
II - The buoyancy force acts at the center of gravity of the fluid displaced by the submerged part of a floating object.
III - The weight acts at the center of gravity of the entire object.
IV - The buoyancy force and the weight always act at the same point.
a) Only I and II are true.
b) Only II and III are true.
c) Only I, III, and IV are true.
d) Only II, III, and IV are true.
e) All statements are true.
