Final answer:
Metamorphic transformations occur while the rock is in the solid state. Metamorphism is the process in which a pre-existing rock undergoes physical and chemical changes due to increased temperature, pressure, or exposure to reactive fluids. This results in the formation of a new rock. option c is answer
Step-by-step explanation:
Metamorphic transformations occur while the rock is in the solid state. Metamorphism is the process in which a pre-existing rock, called a protolith, undergoes physical and chemical changes due to increased temperature, pressure, or exposure to reactive fluids.
These changes cause the minerals in the rock to recrystallize, resulting in the formation of a new rock. Metamorphic rocks can form in various temperature and pressure conditions, but they all occur in the solid state. option c is answer
