    Answer : Option D

    Explanation :

    If the original day sediments are subjected to high temperature and pressure, they successively change into rocks, the correct order of which is Shale, Slate, Schist. Beginning with a shale parent, Barrovian metamorphism produces a sequence of metamorphic rocks that goes through slate, and then through phyllite, schist, and gneiss.
