Answer : The correct option is (A).
Explanation :
As we know that a magnet is an object which produces an invisible magnetic field and attract metals like iron, nickel, cobalt.
The magnets have two poles that is a north pole and a south pole.
If you take a magnet and cut a magnet in half then two pieces would separate and form new sets of poles. That means, when we cut a magnet of south-north pole then it gives two pieces of magnet like south-north and south-north pole.
From the given options we conclude that the option A is the representation of original image of magnet.
Hence, the correct option is (A).
