A data analyst works for a condominium development company. The company is undergoing unit number changes. Which of the following would be MOST appropriate to include on the unit inventory sheet…

Displaying both historical and new unit numbers provides full transparency and context for board members, allowing them to track the changes, understand the mapping, and ensure all units are accounted for during the transition. This approach maintains historical reference while reflecting current information.

Creating a new inventory with only new unit numbers lacks the historical context necessary for board members to understand the changes and reconcile previous records.

Deleting historical files is poor data management practice, as it removes critical audit trails and makes it impossible to reconcile past and present records.

A hidden column might obscure important information that board members need to see explicitly for full understanding and accountability during a significant change like unit renumbering.
