Solution
The correct option is A Navigation
The magnetic needle of the compass is freely suspended, which always aligns itself to the North-South direction of Earth. Hence, it is used to find out the directions for navigation.
It deflects in the presence of magents but not magnetic materials. Hence, it cannot detect magnetic materials.
