The correct answer is:
**a** The magnetic field of the magnet can act at a distance, and influence the metal of the door through the paper.
The magnet, even though it is separated from the door by the paper, can still exert its magnetic field and interact with the ferromagnetic material (typically steel) in the refrigerator door. This interaction allows the magnet to hold the paper against the door.
