Solution

The correct option is A heat and pressure
Metamorphic Rocks are rocks that have changed form due to heat and pressure. Metamorphic comes from the Greek words meta and morph. Meta means change and morph means form. Metamorphic rocks were once sedimentary, igneous or even other metamorphic rocks that have been changed by heat and pressure.
