Hey there!
Here is your answer:
The proper answer to this question is a "igneous rock".
Reason:
Metamorphic rock: Formed by heat and pressure under the Earths crust.
Sedimentary rock: Formed by deposition in rivers and pressure causes the rocks to compact.
Igneous rock: The cooling of lava and it crystalizes.
Therefore the answer is Igneous rock.
