Answer:
Igneous Rock
Step-by-step explanation:
Igneous rocks start as lava, then it cools down, and was put under pressure. It’s not a metamorphic rock because it was already a rock, just things had happened to the rock to make it a metamorphic rock, and it’s not a sedimentary rock because they were formed from sediments, and so since it did not form or start out as lava, it is not a sedimentary rock. Igneous rock is the only rock that started as lava, therefore the answer is igneous rock.
