The command to rename a Delta Lake table primarily focuses on updating the reference for the table in the metastore without altering any of the underlying data. When a table is renamed, the existing data, stored in the underlying Delta Lake files, remains intact and unchanged. This ensures that all references to the original table can still access the same dataset, providing a seamless transition to the new table name.

In the context of Delta Lake's transactional guarantees, this rename operation is efficient and maintains the integrity of the data. Thus, the statement that the table reference in the metastore is updated while no data is changed accurately reflects the behavior of the rename operation.

The other options describe scenarios that do not occur during a standard rename operation. The renaming does not create a new Delta transaction log; instead, it simply reflects the change in the original log. Additionally, there is no need to drop and recreate files or metadata, as the data structure remains stable through this renaming process.
