Brief Explanations:

Metamorphic rocks are formed by the transformation of existing rock types (either igneous, sedimentary, or other metamorphic rocks) in a process called metamorphism, which means "change in form". In the rock - cycle diagram, the rocks labeled with the process of "metamorphism" are metamorphic rocks.

Answer:

The rocks connected by the arrows labeled "metamorphism" are the metamorphic rocks. Without specific labels on the rocks in the image, we can't name them specifically, but they are the ones undergoing or formed by metamorphism.
