b. do mice grow faster when they eat cheese or when they eat peanut butter?
c. do big mice make better pets than small mice?
d. are mice that eat cheese prettier than mice that eat peanut butter?

the correct answer is 4) heat and pressure

metamorphic rocks arise from transformation of existing rocks types, in a process called metamorphism. during metamorphism the original rock(prolith) change into metamorphic rock by heating (150-200c) and pressure of more than 1000 bar. the original rock can be sedimentary, igneous, or existing metamorphic rock.
