Answer:

1)Phyllite

Explanation:

The rock which has undergone more temperature and pressure conditions is Phyllite which is also known as Gneiss.

Schist and Phyllite are produced by the process of medium to high grade metamorphism. But in some cases Phyllite is produced by high grade metamorphism when compared to schist. The Low-grade metamorphic rocks always tend to be fine-grained. High-grade metamorphic rocks are often tend to be coarse-grained.

Phyllite is a high grade metamorphic rock,which means it has been subjected to higher temperatures and pressures than schist. Phyllite is formed by the metamorphosis of granite, or the sedimentary rock. Gneiss/Phyllite displays distinct defoliation, representing the alternating layers composed of different mineral forms.
