D. East and West of earth in opposite direction
Check answer and explanation
Answer: North and South poles of earth respectively
Explanation When a magnet is suspended freely , its north pole will point towards the Earth's magnetic South pole (which is located near the Earth's geographic North pole), and its south pole will point towards the Earth's magnetic North pole (which is located near the Earth's geographic South pole). This is because opposite poles attract, and the Earth's magnetic field is strong enough to align the magnet's poles.
