Every step explained - no skipped algebra.
Slate is a metamorphic rock that originates from the sedimentary rock shale. Under moderate heat and pressure conditions, shale undergoes metamorphism where its clay minerals realign to form fine-grained, foliated slate. This transformation enhances slate's durability and creates its characteristic cleavage planes.
Final Answer: Option A - Shale
