Option (B)

Explanation:

The metamorphic rocks are formed directly from the previously existing rocks of all the three kinds such as sedimentary, igneous and other metamorphic rocks. This type of rock is primarily found in the convergent plate boundaries where the rocks are subjected to extreme pressure and temperature condition, resulting in the increasing grade of metamorphism, which is known as the prograde metamorphism. The rocks alters and give rise to the formation of metamorphic rocks, such as slate, phyllite, schist and gneiss.

Thus, the correct answer is option (B).
