A.   When two plates collide at their continental margins, their deformable seaward rock containing marine organisms crumples up to the top of the resulting mountains.

B.   The rocks at the top of these mountains that contain fossils are oceanic terranes, which are blocks of rock that used to be various parts of oceanic crust. Thicker oceanic blocks of rock were tectonically moved toward the oceanic trench, colliding with the crustal rocks because they were too large to subduct.

C.   The rocks at the top of these mountains that contain fossils are oceanic terranes, which are blocks of rock that used to be various parts of oceanic crust. Oceanic blocks of rock were tectonically moved toward the oceanic trench, colliding with the crustal rocks because they were too large to subduct due to the fact that they contained fossils.

D.   The rocks at the top of these mountains that contain fossils are oceanic terrains, which are blocks of rock that used to be various parts of oceanic crust.
