Answer
Answer:
D
Explanation:
Step1: Recall geological principle
In undisturbed rock - layers, older fossils are in lower layers.
Step2: Identify layer of fish fossil
Assume the fish fossil is not in layer D.
Step3: Determine older layer
Layer D is the lowest layer among A, B, C, and D, so fossils in layer D are older.
