If magnetic lines are close, then the magnetic field has a lot of magnetic lines of force packed together. This translates into a large number of flux lines per unit of area through which they're passing. A large number of flux lines per unit area means a high field density. High flux density means the magnetic field is strong compared to a field where the flux lines are not as close together.
there is more magnetic force in that region on a particle.
It means that the magnets are closer together
Magnetic fields are bascially lines of force caused by magnetic poles. It is invisible, but you can track how the field lines are formed doing a small experiment. Spread some iron fillings on a tray. Then bring a magnet up close to the iron fillings but not too close. You can observe that the iron fillings move into the field lines of the magnet that you brought up close. That's a miniature of a magnetic field. The earth's magnetic field is much bigger.
In a uniform magnetic field the imaginary magnetic lines of force are parallel to each other. But in case of non uniform they are not parallel
The closer the magnetic field lines, the stronger the magnetic force in that area.
The list of choices submitted with the question containsno correct description of magnetic field lines.

Lines of Force
They are called the magnetic field lines.
Magnetic field lines don't cross.
Field Lines Show Magnitude and DirectionWhen the lines of the magnetic field are close together the magnetic field is strong. In a region where the line density is high, one says that it has great intensity or strength. Technically, the density of lines is proportional to the magnitude of the field.The direction that magnetic field line are oriented provides the information on the direction of the field, with the convention that the lines have arrows drawn so the lines exit from the North pole of a permanent magnet, or equivalently, the arrows point in the direction that the North end of a compass needle would point if placed on the line.
In a uniform magnetic field the imaginary magnetic lines of force are parallel to each other. But in case of non uniform they are not parallel
The direction of magnetic field lines are from north to south
The closer the magnetic field lines, the stronger the magnetic force in that area.
