The meteorite, Hoba, is most similar in composition to which layer (s) of Earth's interior

The correct answer to the following question will be "Core".

Explanation:

The interior of the globe becomes largely distinguished by its composition including depth into the crust, mantle, as well as core. The core has always been mainly made up of iron, with such lower nickel content including a few percent oxygen levels. It seems to be incredibly hot. The energy released seems to be solvent whereas the internal structure is strong even if it is warmer also because the pressure at a certain complexity would be so much higher.

So that the above is the right choice.
