B
The older sedimentary layers contain only shell fossils (invertebrates), while the younger layers show fossils with bony skeletons, indicating that animals with shells appeared before animals with bony skeletons. The other choices misinterpret the evidence (vertebrates did not evolve directly from all invertebrates, there’s no clear evidence that plants and bony animals appeared simultaneously, nor that land and marine animals evolved together from the given layers).
