Nothing. That's exactly what a compass does ... as long as it's free to turn,
and there are no ferrous metals or other sources of magnetic fields nearby.

The term "compass direction" means a direction shown by a magnetic compass, one whose needle will be drawn to a north-south alignment. When at a location and facing a certain direction, the "compass direction" is the one at the top (front) of the moving compass rose. If a location is in that direction, it is the indicated compass direction from the current point.On a map, the direction from one point to another is indicated by the up-down and left-right line between the points, and the compass directions are indicated by a compass rose on the map.

That would be latitude or longitude.
B. A magnetic field line shows the direction a compass needle would align in a magnetic field.
We can use iron filings, a magnetic compass, or a Hall probe to find the shape of a magnetic field. Iron filings line up along magnetic field lines, a magnetic compass shows the direction of the field, and a Hall probe can measure the strength of the magnetic field at different points.
The line with which a compass aligns is called the magnetic meridian. This line indicates the direction of the Earth's magnetic field at a specific location. Compasses point towards magnetic north, which is generally close to, but not the same as, true north, due to the Earth's magnetic field being irregular.
A magnetic field line is an imaginary line that represents the direction a magnetic compass would point when placed at any point in space. The lines form closed loops around a magnet or current-carrying wire, flowing from the north pole to the south pole in a continuous path. The density of field lines indicates the strength of the magnetic field.
A compass needle will align itself with a magnetic field. It will want to lie along the magnetic field lines, or lie parallel to the lines of force of the magnetic field it is interacting with.
Earth acts like a giant bar magnet with a North and South pole, which creates a magnetic field. A compass needle is a small magnet that aligns itself with Earth's magnetic field to point towards the magnetic North pole. This allows users to determine their direction by reading the compass needle.
The magnetic meridian in compass surveying is the line passing through a compass needle when it is freely suspended and allowed to align with the Earth's magnetic field. It represents the direction of the magnetic north pole at a particular location on the Earth's surface. It is an important reference in compass surveying for determining directions.
From that list, I'll have to go with 'B'.
The tangent to a magnetic field line at any point indicates the direction of the magnetic field at that specific location. This is because the tangent line represents the direction a compass needle would point if placed at that point on the field line. The magnetic field lines themselves flow from the north pole of a magnet to its south pole, with the tangent pointing in the direction the magnetic field would act on a north pole.
A needle on a compass aligns itself with the Earth's magnetic field. The needle is magnetized, with one end pointing towards the Earth's magnetic north pole and the other end pointing towards the magnetic south pole. This alignment allows the needle to point in the direction of magnetic north.
a compass points the magnetic north pole,because the earth is tilted on an axis of 23 degrees, while spinning on this same axis.that is why a compass points to magnetic north and not true north.
A plotting compass is a small magnet which is suspended and is free to rotate. When it is near a magnet, the compass will always point in a particular direction (the north pole's direction) becasue of the force of the magnetic field.
