Answer: Hope this helps you
B
Explanation:
A: Lava is one material, however the igneous rock forms crystals while cooling so it is not A.
B: Yes, it may be B since magma and lava are the two materials that form igneous rock, but let's look at the other answer thought.
C: The rock forms crystals, and an intrusive rock is a king of igneous rock so it can't be c.
D: Igneous rocks can be an intrusive rock which isn't a material that makes it. Plus, sediment from rocks form sedimentary rocks completely removing D from thought as it is completely absurd.
This means the answer is B as it is the only one that actually makes sense. (Brainliest?)
