Which of the following would contribute to assurance of the ability to transfer an application from one database to another?

The use of SQL facilitates portability. Verification of import and export procedures with other systems ensures better interfacing with other systems, analyzing stored procedures/triggers ensures proper access/performance, and reviewing the design entity-relation model will be helpful, but none of these contribute to the portability of an application connecting to a database.
