Explanation:

All three statements about metamorphism and metamorphic rocks are correct.

The first statement is correct. Metamorphism is indeed the process of recrystallization and reorganization of minerals within a pre-existing, consolidated rock, known as the parent rock. This process occurs under conditions of high temperature and/or pressure, which lead to physical and chemical changes in the rock without melting it.

The second statement is also correct. Foliation is a common feature of many metamorphic rocks. It refers to the repetitive layering or banding in the rock, often caused by the reorientation of minerals under directional pressure, leading to a layered or banded appearance.

The third statement is correct. Dynamic metamorphism refers to the metamorphism that occurs mainly as a result of mechanical deformation, with little or no chemical change. This typically happens in areas with high stress, such as fault zones, where rocks are subject to intense pressure and shearing forces, leading to physical reorganization of the rock structure.

Therefore, all three statements are correct.
