According to the given code, the Full light being ON indicates that the weight of the vessel is 500 pounds or more. Therefore, Statement A is true. Rung No.3 has no connection with the Full light being ON or OFF, so it is always true regardless of the Full light. Therefore, Statement B is also true. On the other hand, Rung No.1 states that the Half light is ON when the weight of the vessel is between 250 to 499 pounds. Since the Full light being ON contradicts the Half light being ON, Statement C is always false when the Full light is ON. Hence, the answer is D.
