Nope, you are talking about MANAGED LOCATION (from Unity). In the question states LOCATION (not Unity based), which is not managed https://docs.databricks.com/en/sql/language-manual/sql-ref-syntax-ddl-create-schema.html

Every unmanaged(external) table creation needs to put keyword LOCATION despite if database, that table resides, is put with LOCATION sententece. So B is incorrect. D is correct because the sentence to creates the table is a managed table. https://docs.databricks.com/en/lakehouse/data-objects.html

This is because the storage container is mounted to /mnt/finance_eda_bucket, and the code executed by the finance team member would create an external table in that location.

Answer D. The use of the LOCATION clause with a DBFS path (/mnt/finance_eda_bucket) suggests that Hive Metastore and DBFS location are being used. The answer is correct in the context of Hive Metastore and DBFS location, but if Unity Catalog (UC) is in use, the result would be an external table, not a managed one.

Correct answer D. just did a test. As with DBR12.2, UC databases are not supported with location on dbfs, but s3/abfss. However, Hive_metastore databases are supported with location on dbfs. Then, a table created in this database IS a managed table, as verified with describe extend command.
