Which of the following are Metamorphic rocks?

A. Gneiss and Mafic

B. Gneiss and Schist

C. Schist and Mafic

D. Schist and Chalk

Answer: Option B

Solution(By Examveda Team)

Schist and gneiss are produced by medium to high grade metamorphism. In some cases gneisses are produced by higher grade metamorphism than schists. Low-grade metamorphic rocks tend to be fine-grained (the newly formed metamorphic mineral grains that is). High-grade metamorphic rocks tend to be coarse-grained.
