In the diagram the solid green line represents earths rotational axis and the dashed red line represent the magnetic field axis which diagram accurately shows earths magnetic field

Option B)

Explanation:

As we know that Earth's magnetic poles are inclined at some angle with the rotational axis of the Earth.

So here the magnetic poles must be inclined at some angle with the rotational axis of Earth

Now we know that magnetic field of earth originates from the south pole of earth and terminate near the north pole of earth

So magnetic poles of earth are opposite to the geographic pole of earth

So magnetic field will originate near the south pole and go near the north pole of earth

so here correct answer must be Option B)
