Answer:
The interior of Mars is probably solid.
Explanation:
The Earth's magnetic dynamo is generated by a current in the interior of the planet that is a result of the eddies that form thanks to the outer core being molten.
Since Mars is a smaller planet and is located twice as far from the Sun as Earth, it cooled faster and likely no longer has a molten or semi-molten interior. The cooling of the interior of the planet would have shut off the magnetic process and could explain why the modern Martian atmosphere is so tenuous.
The change of air temperature with height is the environmental lapse rate. The correct option among all the options that are given in the question is the second option or option "B". It is a fact that heat can never leave or enter a system and all the changes of temperature take place internally. I hope it helps.
