Which workflow action could Tiffany use to keep a record of the original request while also allowing updates?

The action Tiffany should use is to copy the row. This option allows her to create a duplicate of the original request, thereby preserving the initial data while also enabling her to make any updates or modifications to the new copy. By using the copy function, the original request remains intact for future reference, and she can work on the updated version without losing the context or details of the original request.

In contrast, moving a row would relocate it to a different sheet or location, which wouldn't retain the original context in the starting location. Deleting a row removes it entirely from the sheet, losing all records associated with that request. Archiving a row typically symbolizes that it's no longer actively being worked on, but it wouldn't allow for further immediate updates to the content of the request. Thus, copying the row is the optimal solution to fulfill both requirements of keeping the original request and allowing for subsequent updates.
