The list of choices submitted with the question contains
no correct description of magnetic field lines.
A.They never cross. B.They begin on north poles and end on south poles. C.They don't affect the magnet that created them. D.Field lines that are close together indicate a stronger magnetic field
All of them basically,
straight parallel lines
The magnetic field lines are arranged circularly around the wire.
Magnetic field is made up of magnetic lines.
The magnetic force of a magnet is strongest at its poles. This is because the field lines of the magnetic field are most concentrated at the poles where they enter and leave the magnet. At the poles the magnetic field is strongest and the force is the greatest. The north pole is where the magnetic field lines enter the magnet. The south pole is where the magnetic field lines leave the magnet. The magnetic field lines are most concentrated at the poles. The magnetic force is greatest at the poles.
The closer the magnetic field lines, the stronger the magnetic force in that area.

Magnetic fields are produced because of moving electric charges, and visualizing the very complex mathematical relationships that fall under the magnetic field might become much easier if magnetic field lines were used. A higher density of field lines means a stronger magnetic field. Keep in mind that those lines do not actually exist; they are drawn only to visualize the strength of the magnetic field.
They are called the magnetic field lines.
Magnetic field lines don't cross.
Lines of Force
