Answer 1

The correct option is D

All the three

All the given statements are correct.
A compass is an instrument for determining directions, as by means of a freely rotating magnetized needle that indicates magnetic north.

The Earth is a magnet that can interact with other magnets. Thus, the north end of a compass magnet is drawn to align with the Earth's magnetic field to indicate the north and the south directions of the earth.
