Hint:
In this question we have to use the concept of magnetism and magnetic field lines. A magnetic field is created around a magnet when it is positioned. Magnetic field lines can be used to visualise this magnetic field. The magnet's magnetic field is strongest where these magnetic field lines are densest.
Complete step by step solution:
We know that a bar magnet is composed of a ferromagnetic substance and it can be of any shape and size. In any magnet, there are two poles named ‘North-Pole’ and ‘South-Pole’ such that the magnetic field lines originate from the North pole and end at the South pole.
Since a magnet contains both the North and South pole, the options (A) and (B) are incorrect and therefore, a magnet is treated as a di-pole (which means having two poles at the same time). Even if we break a bar magnet from the middle still there will be two poles in both the pieces.
Also, Monopoles do not exist in magnetism, therefore option (D) quadrupole (four single monopoles) is also incorrect.
Thus, the ultimate individual unit of magnetism in any magnet is called Dipole.
Hence, the correct option is (C) Dipole.
Therefore, the correct option is C.
Note:
Since this is a problem related to a bar magnet and uniform magnetic field (conceptual problem) hence, it is essential that given options must be analyzed very carefully to give a precise explanation. While writing an explanation for this kind of conceptual problem, always keep in mind to provide the exact reasons in support of your explanation.
