Igneous intrusion "D" is the Oldest

Layers, E, C, B and A were deposited after.

Layer E is the oldest, then C, then B.

Next, igneous intrusion "D" melted through the first three layers.

Finally layer A was deposited on top.

Layer C is the oldest layer, then B, then A.

Next igneous intrusion "D" melted through all the layers.

Finally, all the rock layers slipped at fault "E".

Layer C is the oldest layer, then B, then A.

Next, all the rock layers slipped at fault "E".

Finally, igneous intrusion "D" melted through all the layers.

All the rock layers slipped at fault "E".

Then layers C, B, and A were deposited.

Finally, igneous intrusion "D" melted through the layers.
