Solution
The correct option is A
Bar magnet
Bar magnets can be used for finding geographical directions, as they always align themselves towards the North-South direction. The magnetic south pole of Earth is also its geographical north pole and vice-versa. The north pole of the suspended magnet gets attracted to the magnetic south pole of Earth (geographical north pole) and vice versa.
