Final Answer :
D
Explanation :
Fine-grained clastic rocks, such as shale, are made of very small particles that are not easily seen with the unaided eye. These rocks tend to be more easily eroded compared to coarser-grained rocks because the smaller particles can be more readily detached and transported by erosive forces.
