The cross-section diagram below shows some rocks and geologic structures as seen in the face of a vertical cliff. There are four horizontal layers of sedimentary rock, two cross-cutting bodies of igneous rock, and a fault that cuts and offsets some of the sedimentary and igneous rocks. The bottom layer of sedimentary rock, at the bottom of the diagram, is D, and the layer of sedimentary rock on top of D is labeled G. An irregular body of igneous rock labeled E angles up and cuts through layers D and G. The fault, F, cuts and offsets D, G and E. On top of layer G is sedimentary rock layer A, and on top of layer A is the top layer of sedimentary rock, C. Another irregular body of igneous rock, labeled B, angles up from the bottom to the top of the diagram, cutting across all the other bodies of rock. Going from oldest to youngest, what is the correct relative age sequence?
