The correct answer is: B. declination
Declination is the angle between true north and magnetic north. It is caused by the Earth’s magnetic field not being aligned with its axis of rotation. The declination varies from place to place and changes over time.
Azimuth is the angle between the north direction and a line to a point of interest, measured clockwise from north.
Local attraction is a magnetic field that is not caused by the Earth’s magnetic field. It can be caused by nearby objects, such as large metal objects or underground deposits of ore.
Magnetic bearing is the direction of a line from the observer to a point of interest, measured clockwise from north, taking into account the declination.
