A freely suspended magnet rests in the geographic north-south direction.
Earth has two geographic poles, the North Pole and the South Pole. They are the places on Earth's surface that Earth's imaginary spin axis passes through. Our planet also has two magnetic poles, the North Magnetic Pole and the South Magnetic Pole just like a bar magnet. The magnetic poles are near, but not quite in the same places as, the geographic poles. The needle in a compass points towards a magnetic pole. Earth's North Magnetic Pole is actually the south pole of the Earth's geographic poles and vice-versa.
Hence, a freely suspended magnetic needle point in geographic north-south direction. The magnetic compass is the device that uses this principle. A magnetic compass contains a magnetic needle pivoted in a horizontal plane that indicates the direction of magnetic north at points on the earth's surface. It is an instrument that uses a magnetized steel bar to indicate direction relative to the earth's magnetic poles.

Statement A is false because null points are on the axial line when the north pole points north. Statement B is false because at the null point, the magnetic field of the magnet is equal and opposite to the horizontal component of the earth's magnetic field, not zero.

The best evidence is to test it by taking a direction compass and seeing it where the north position will point and you will see that it will always point to the north and south pole.

The north pole of the normal magnet points in the north direction of the earth. Thus by suspending a bar magnet freely, it aligns in the north-south direction.

The north end of compass needle points approximately towards north pole, which is geographic north of the earth , which is south pole of earth's magnet as per convection and attraction law.

The north-seeking pole of the magnet, or simply the north pole. The opposite end is called the south pole.

The north pole of the normal magnet points in the north direction of the earth. Thus north direction is found first with the help of the magnet..

A freely suspended magnet always points in the north south direction as earth behaves as large magnet. the north pole of the earth's magnet attracts the south pole of the magnet and vice versa.

The compass needle acts as a freely suspended magnet which points in north-south direction under the influence of earth's magnetic field lines. So, a small plotting compass can be used to plot a magnetic field.
