The diagram below shows different layers of sedimentary rocks.
 Picture showing seven layers of rocks of different colors labeled A, B, C, D, E, F, and G from top to bottom; A and B are parallel horizontal layers at the top of the diagram and C, D, E, F, and G are slanted layers with C closest to the surface and G at the bottom.
 Based on the diagram, which of these inferences is most likely correct?
 A.Layer A is older than Layer B.
 B.Layer C is older than Layer E.
 C.Layer F is younger than Layer D.
 D.Layer B is younger than Layer G.
