D. Metamorphic, Sedimentary
Explanation:
When both plates collide, heating and high pressure causes recrystallisation of minerals that have been formed before. New mineralogical facies would surface. This is a metamorphic change and the rock becomes a metamorphic rock.
Due to the weathering of this rock, materials are eroded, transported into basins of deposition to form new sedimentary layers. The rock that forms through the compaction and cementation of the sediments is a sedimentary rock.
