Answer:
C
Step-by-step explanation:
The presence of metamorphic rocks is most likely evidence of high pressure.
Metamorphic rocks are rocks that are formed from the transformation of other rocks. They could be igneous or sedimentary rocks that have been subjected to high temperature, pressure, or hot mineral fluid and then become metamorphosed into another type of rock.
Sometimes, metamorphosis of rocks happens from the combination of all the factors. Example include the metamorphosis of granite to gneiss and that of shale to schist.
Hence, the presence of metamorphic rocks is most likely the presence of high pressure.
Correct option: C.
