Hint
We know that magnetism is defined as the phenomena that are mediated by magnetic fields. Electric currents and the magnetic moments of elementary particles give rise to a magnetic field, which acts on another combined phenomenon of electromagnetism. The most familiar effects occur in ferromagnetic materials, which are strongly attracted by magnetic fields and can be magnetized to become permanent magnets, producing magnetic fields themselves. Based on this concept we have to solve this question.

Complete step by step answer
A magnetic field is a vector field that describes the magnetic influence on an electric charge of other moving charges for magnetized materials. A charge that is moving in a magnetic field experiences a force perpendicular to its own velocity and the magnetic field.
Magnetic field lines are a virtual representation of the invisible lines of force in a magnetic field. By convention, the lines trace the force from the north to south pole of a magnet. The distance between the lines indicates related strength of the magnetic field.
Since, Magnetic fields extend from North Pole to South Pole, only option C satisfies the same as we can see the magnetic field lines moving from north pole to south pole in the bar magnet.

Therefore, the correct answer is Option (C).

Note
We should know that two magnetic field lines can never intersect each other because at their point of intersection there will be two directions at a time which is impossible. If a tangent is drawn at any one point on magnetic field lines then it gives the direction of the magnetic field at that point.
A magnetic field line never crosses another field line. The magnetic field is unique at every point in space. Magnetic field lines are continuous unbroken, forming closed loops. Magnetic field lines are defined to begin on the north pole of a magnet and terminate on the south pole.
