Answer:
C-Changing the S to N
Explanation:
As we know that magnetic field lines originated from North pole of magnet and then terminate into the south pole of magnet.
Now if we put similar poles of magnet in front of each other then we can say that the magnetic field lines of two poles will repel each other and due to this two similar poles have repulsion force.
Similarly if two different poles of magnet will place in front of each other then the magnetic field lines will originate from north pole and terminate at south pole.
This will show attraction force between the poles of magnet.
Now we can see the figure that magnetic field lines are originating from both poles here as well as these lines are repelling each other.
So here both poles must have North pole
So correction here must be
C)-Changing the S to N
