in the diagram below, compare the rock layers below layer e. rock layer d is the youngest layer, and rock…

Brief Explanations:

In geology, the principle of superposition states that in an undisturbed sequence of sedimentary rock layers, the oldest layers are at the bottom and the youngest are at the top. Among the rock - layers below layer E, we need to identify the youngest and the oldest. Since layer D is already given as the youngest among the layers below E, we look for the layer at the bottom - most position among the remaining options below E to find the oldest. Layer A is the bottom - most layer among the options provided below E.

Answer:

Rock layer D is the youngest layer, and rock layer A is the oldest.
