Terrane
A fragment of Earth's crust that has been transported and attached to a continent along a tectonic boundary.
Shear Zones
Regions of the Earth's crust where rocks have been deformed by shear stress, leading to the development of features like stretched and thinned rocks, often seen in tectonic plate boundaries.

Final Answer :
A
Explanation :
Terranes are distinct geological entities or fragments of crust that have been attached to a continent along a fault or shear zone. Their boundaries are often defined by major faults or shear zones, distinguishing them from the surrounding geological formations. They do not necessarily have the same sequence of rocks or match in layers and fossils with adjacent areas, which is part of what makes them identifiable as separate entities.
