In this rock layer diagram there are two unconformities, a fault at E and an intrusion at D. Which unconformity occurred first?  How do you know?

• Intrusion D occurred first because the instrusion has been moved by the fault.
• The fault occurred first because it has moved the intrusion D.
• Intrusion D occurred first because it can be seen in all of the rock layers.
• Fault E occurred first because it is a normal fault.
