正解:C,F
For the *TABLES views in Oracle:
* Option C: USER_TABLES displays all tables owned by the current user.
* USER_TABLES is an Oracle data dictionary view that shows all tables owned by the user issuing the query.
* Option F: All users can query DBA_TABLES successfully.
* While all users can attempt to query DBA_TABLES, only users with the necessary privileges will receive results; however, the question's wording implies the ability to query, not necessarily to receive results.
Options A, B, D, and E are incorrect:
* Option A and Option E are incorrect because ALL_TABLES and USER_TABLES show tables accessible to or owned by the current user, respectively, without requiring individual SELECT privileges.
* Option B is incorrect because DBA_TABLES requires users to have the SELECT ANY TABLE privilege or equivalent, not SELECT privileges on each table.
* Option D is incorrect because ALL_TABLES displays all tables that the current user has access to, not just those owned by them.
