The correct answer is: metamorphic.
Metamorphic rocks are rocks formed from transformation of existing rocks by the influence of pressure, heat or chemically active fluids. Those rocks go through chemical or physical changes-change in form.
The original rock is called protolith and it may be a sedimentary, igneous, or existing metamorphic rock.
Some of the metamorphic minerals are isillimanite, kyanite, andalusite, and some garnet.
