Magnetic poles of Mercury?

[straightshooter]

I believe it's (a). Why, because earth's magnetic field is caused by a solid metallic core with magma surrounding it and since the core and the magma move at different velocities, this causes a magnetic field with an imaginary line that passes through the center of the earth. Perhaps the reason why Mercury's magnetic imaginary line doesn't pass through the center is because it is arranged in the opposite of the earth where the core is molten iron and not solid like the earth's core, and outside of Mercury's core is solid rock instead of magma like the Earth has. This would also cause a magnetic field on Mercury but not in the same way as Earth's magnetic field with an imaginary field line going through the middle of Earth.

The magnetic poles of Mercury are intersected by an imaginary line that does Not pass trought the center of the planet. If the magnetic poles are fixed in space(even thought the planet rotates), what could we surmise about the origin of our field?
Plz tell the reason, and I don't think it will be B

a. the planet's core is molten iron.
b. not much, for we nee more information besides observations of the shape and dynamics of the planetary magnetic field.
c. the nature of the magnetic field is due mainly to the influence of the solar wind
d.the planet's core is a solid, magnetic material.
