Best answer
Right choice is (d) W0 = Wcrew + Wpayload + Wfuel + Wempty

Best explanation: The design take-off gross weight is the total weight of the aircraft. It consists of every possible segments either it is payload or fuel. Hence, it can be seen as the addition of the all possible weight in an aircraft.
