B)iron
C)both the same

Question

The large block of wood has a greater volume than the small block of iron, which means it displaces more air and experiences a greater buoyant force. Since both register the same weight on the scale, the wood's greater buoyancy means it must have a greater mass to still weigh 2000 N despite the upward buoyant force.
