Regarding privileges in Oracle:
Option A: Dropping user FINANCE will automatically revoke SELECT on SCOTT.EMP from user FIN_CLERK.
Dropping a user will revoke all privileges that user has granted to others.
Option B: Revoking SELECT on SCOTT.EMP from user FINANCE will also revoke the privilege from user FIN_CLERK.
Since FINANCE granted SELECT on SCOTT.EMP to FIN_CLERK with grant option, revoking the privilege from FINANCE will also cascade and revoke it from FIN_CLERK.
Options C, D, and E are incorrect because:
Option C: User FINANCE can grant privileges it owns, but CREATE SESSION is a system privilege; unless FINANCE has the 'WITH ADMIN OPTION' for CREATE SESSION, it cannot grant this privilege.
Option D: User FIN_CLERK can only grant privileges to others if it has been given those privileges with the 'WITH GRANT OPTION' and it was not given in this case.
Option E: User FINANCE can grant privileges on SCOTT.EMP to other users only if it has those privileges with 'WITH GRANT OPTION'. If the privilege was just SELECT with GRANT OPTION, it cannot grant ALL privileges.
