Which coordinate system (one-dimensional, two-dimensional, three-dimensional) should be chosen to determine

Which coordinate system (one-dimensional, two-dimensional, three-dimensional) should be chosen to determine the position of such bodies: a) a chandelier in the room b) an elevator c) a submarine d) an airplane on the runway.

To determine the position of the chandelier in the room, you must choose a two-dimensional coordinate system, since the chandelier is on the ceiling, and to indicate its exact location, you need to know the x and y coordinates relative to the ceiling.

To determine the position of the elevator, it is sufficient to select a one-dimensional coordinate system, since the elevator moves only vertically.

To determine the position of the submarine, it is necessary to select a three-dimensional coordinate system, since the boat also has a diving depth;

To determine the position of the aircraft on the runway, a two-dimensional coordinate system is sufficient, since at this moment it is on the ground and moves only back and forth and left and right.
