Solution

The correct option is D
At all the places within the earth's magnetic field

A compass is an instrument for determining directions. It has a freely suspended needle that rests in the north-south direction, thus indicating which cardinal direction we face at any point in time. It works at all the places within the Earth's magnetic field because the magnet aligns sin same direction due to Earth's magnetic field.
