Universal Containers has a highly integrated environment with significant process orchestration between systems. When refreshing UAT, Objects that have external Ids from Production no longer point to valid External Ids in the UAT environment. What should an Architect do to resolve this?

A. In the post refresh plan, modify external ids to a known valid set of values for UAT Most Voted
B. Mask the External Id so nobody can see the production value
C. Let UAT point to production integrations and rollback each transaction after it finishes
D. Delete all the data and use an Automated testing tool to create new data across all the systems in UAT
