The pattern of iron fillings around the magnet depicts that like poles repel because the magnetic lined bend away from each other. Thus, option C is correct.
What are magnetic field lines?
The North Magnetic Pole would move via magnetic field lines, which are hypothetical lines. The magnet's oppositely polarized poles attract and repel one another.
Since the magnetic field lines inside the magnet run from the south pole to the north pole, Never do magnetic field lines cross one another. A closed loop is formed by magnetic field lines.
Because magnetic force lines are bending in the direction of the south pole in the illustration, like poles repel one another. If the magnetic lines are bent away from one another, like poles repel one another.
Thus, image given has the presence of lines bending away from each other, thereby are like poles repel. Hence, option C is correct.
