Answer: C) Slate, phyllite, schist, and gneiss are found in areas of continental collision
Explanation:
The only true statement among these options is option C: Slate, phyllite, schist and gneiss are all metamorphic rocks. This means that, when exposed to incredibly high levels of pressure and temperature, they will change radically (basically, they recrystallize into brand new minerals and structures) while still holding a solid form.
