Solution

The correct option is D

Magnetic compass


A magnetic compass is a tool used for navigation. A magnetic compass aligns in North-South direction. This is because Earth behaves like a huge magnet and the poles of the Earth behave like poles of a huge bar magnet. As such, a freely suspending magnet gets attracted to the opposite poles and rotates in the direction of attraction. This direction is the North-South direction.
