Solution

The correct option is A ​​​​​​Magnetic flux

Magnetic flux is a measure of the total number of field lines passing through an area. It depends on the strength of the magnetic field as well as the area which we consider to measure the flux. Flux through an area closer to a magnet's poles will be more compared to flux through the same area which is further away.
