Solution

The correct option is C

The Earth has a magnetic field and the pointer is magnetic.


A compass has a pointer, which has a bar magnet inside it. The bar magnet aligns itself in the North-South direction when freely suspended due to the Earth's magnetic field. Hence, a compass has a small balanced pointer that points towards the North-South direction.
