Answer:
C- Law of Superposition
Explanation:
The Law of Superposition states that it is logical for older species (for example fossils or rock materials) to support the weight of younger species. This implies that the older species will be at the bottom while the younger will be at the top. Conversely, we can say that the younger species is superimposed on the older ones.
So Layer D is younger than Layer C because D comes after C in the alphabet.
