The statement that accurately describes the geologic features is option D occurred before A.
In the context of relative geologic time, the principle of superposition tells us that in undisturbed layers of rock, the oldest rocks are at the bottom, and the youngest are at the top.
In this case, D is depicted as the deepest layer, indicating that it formed first. A, on the other hand, is shown above D, indicating that it formed later, after the deposition of the horizontal layer (B) that covers it. Therefore, D occurred before A in the sequence of geologic events.
