Where is metamorphic rock found in the rock cycle?

Point B is generally associated with the formation of igneous rock, which occurs through the cooling and solidification of magma or lava. This process does not involve the heat and pressure needed to create metamorphic rocks, making this choice incorrect for identifying where metamorphic rock is found in the rock cycle.

Point A is typically where sedimentary rocks are formed through the processes of sedimentation and lithification. While sedimentary rocks can eventually become metamorphic rocks, Point A itself does not represent the environment conducive to metamorphic processes, as it lacks the necessary heat and pressure.

Point D often indicates the location of weathering and erosion, which are processes that break down rocks into sediments. These processes are contrary to the conditions required for metamorphic rock formation. Thus, Point D cannot be where metamorphic rocks are found in the rock cycle.
