(单选题)19: An application uses embedded dynamic SQL to connect to a remote DB2 server and inserts data into the CUST.ORDERS table on that remote DB2 server. To enable access of the remote DB2 server, Administrator FOO needs to create a package with default options such that BAR is the only non-administrative user that can use this package on the remote DB2 server. Which statement describes the privileges that must be granted and/or revoked by FOO to accomplish this?
A: BAR requires EXECUTE privilege on the package and UPDATE privilege on CUST.ORDERS, and the EXECUTE privilege for the package must be revoked from PUBLIC.
B: BAR requires EXECUTE privilege on the package and INSERT privilege on CUST.ORDERS, and the EXECUTE privilege for the package must be revoked from PUBLIC.
C: BAR requires EXECUTE privilege on the package and INSERT privilege on CUST.ORDERS, and the REFERENCES privilege for the package must be revoked from PUBLIC.
D: BAR requires EXECUTE privilege on the package and UPDATE privilege on CUST.ORDERS, and the REFERENCES privilege for the package must be revoked from PUBLIC.
