Identifying the fossils in a layer of rock is an example of a relative dating method. The correct option is D.
Researchers use some kind of clock to establish the date that a rock or fossil was formed in order to determine its age. In order to reliably date historic events, geologists frequently use radiometric dating techniques, which are based on the natural radioactive decay of specific elements like potassium and carbon.
Scientists use relative dating to determine whether a rock layer is "younger" or "older" than another. This would also imply that the oldest forms of life in a particular rock formation would be represented by fossils discovered in the area's deepest layer of rocks.
Thus, the ideal selection is option D.
