Step 1: Understanding the Question:
This question tests knowledge of metamorphic rocks and their parent materials.
Step 2: Detailed Explanation:
Shale on metamorphosis changes to slate (C).
Shale is a sedimentary rock.
Under heat and pressure, it metamorphoses into slate, which is a foliated metamorphic rock.
Other rocks:
- Quartzite (A): Metamorphosed sandstone.
- Marble (B): Metamorphosed limestone.
- Basalt (D): An igneous rock.
Thus, shale metamorphoses into slate.
Step 3: Final Answer:
Thus, shale on metamorphosis changes to slate, which corresponds to option (C).
