Final answer:
When an elevator is moving downward with a constant velocity, the apparent weight of each person remains unchanged.
Step-by-step explanation:
When an elevator is moving downward with a constant velocity, the apparent weight of each person will be unchanged (C).
Even though the elevator is moving downward, the constant velocity means that there is no net force acting on the person in the elevator. Therefore, the person's weight remains the same and there is no change in their apparent weight.
