I believe the correct answer would be they join north pole to south pole. The direction of these lines always goes from the direction of north to south pole. These lines forms loops in order to favor the way which requires or has less resistance. Hope this helps.

Magnetic field lines are presentation of magnetic field on paper

There is no real existence of magnetic field lines in the surrounding of a magnetic material but it is an hypothetical way to represent the magnetic field variation.

There are several rules to draw the field lines on paper which are as following

1. magnetic field lines start from north pole and ends at south pole

2. density of field lines shows the strength of magnetic field

3. tangent to the magnetic field line represents the direction of magnetic field so there can not exist a point where two magnetic field lines will intersect

so as per all above rules the correct answer should be

A. They join north pole to south pole.

Imagine that Earth stops orbiting the Sun but continues to rotate in place about its own axis at its current rate. In this case,

Answer:

The length of the solar day will get shorter.

Explanation:

The blue planet Earth not only rotates around it's own axis but also rotates around the Sun and everyday it moves a little bit around the axis.
Since the speed of the Earth's rotation on it's own axis and around the Sun is constant we don't feel the effects of the rotation.We can only feel the motion if the earth changes it's rotation speed.
If by any means or chance the Earth stopped spinning (stopped rotation) then the atmosphere surrounding the Earth would be in motion and all the Earth's land would be scoured clean.
