Question

Quizplus · Accepted Answer

Slate is a metamorphosed shale, so option B is the best choice as it describes shale that has undergone metamorphism to become slate. Option A (granite) is incorrect as it is not a type of shale and option C (marble) is incorrect as it is not a type of foliated rock. Option D (limestone) is also not correct as it is a sedimentary rock and not a metamorphic rock like slate.
