The correct label for the arrow from the picture of obsidian (an igneous rock) to the picture of slate (a metamorphic rock) is:
C. heat and pressure
This is because slate forms from the metamorphism of shale, which involves exposure to heat and pressure, rather than any direct process related to cooling or erosion.
