C)same on each if volumes remain the same.

Question

The buoyant force on an object is determined by the volume of fluid it displaces when submerged, not by its contents. Since both life preservers have identical volumes and are fully submerged, the volume of water displaced by each is the same, leading to an equal buoyant force on each, according to Archimedes' principle.
