When a tenant database is renamed in SAP HANA, the operation requires the database to be temporarily taken offline and then brought back online. The system automatically stops and then restarts the tenant database to apply the name change. As part of this process, the physical directory paths on the file system corresponding to the tenant's data, log, and trace files are renamed to reflect the new database name, ensuring consistency between the logical database name and its physical storage structure.

B. The tenant database backups are renamed.

This is incorrect. The backup catalog is updated to associate existing backups with the new database name, but the physical backup files themselves are not renamed.

D. The tenant database is unloaded from memory.

While stopping the database does unload it from memory, this option is less precise. The official process is a full stop and restart, making "stopped" the more accurate and direct description of the action.
