Answer 2

Answer: Igneous rocks are made of B. materials that crystallized from magma or not lava, not from once living things

Explanation: Igneous rocks are formed from the solidification of magma, which is a hot (600 to 1,300 °C, or 1,100 to 2,400 °F) molten or partially molten rock material. Earth is composed predominantly of a large mass of igneous rock with a very thin veneer of weathered material—namely, sedimentary rock.
