As shown in the picture, in windless weather, three packages of goods have fallen from the plane flying horizontally to the right at a constant speed. People on the ground can see this if air resistance is not counted. Because of gravity, there is a difference between the upper and lower positions of the goods after they leave the plane, that is, the relative position of falling early is below. Let's look at the relationship between vertical positions: it turns out that the cargo and the aircraft fly at a constant speed equal to the plane speed level, and the initial speed is equal. After the cargo leaves the plane, it still moves horizontally at the same speed without considering the air resistance caused by inertia, so option C will be formed.

So choose C.
