Explanation / Answer

Part A: By definition, the Buoyant force is equal to the weight of the fluid displaced. Hence the first choice is correct. It is true for all objects partially or fully submerged.

Part B: This is true only for fully submerged objects. Only fully submerged objects displace the fluid equal to their volume. Partially submerged objects displace volume of fluid equal to their partial volume.
