User OE, the owner of the ORDERS table, issues the following command:
GRANT SELECT,INSERT ON orders TO hr WITH GRANT OPTION;
The user HR issues the following command:

REVOKE ALL ON orders FROM hr;
Which statement is correct?

• A. The user SCOTT retains the privilege to select rows from OE.ORDERS.
• B. The user SCOTT loses the privilege to select rows from OE.ORDERS.
• C. The REVOKE statement generates an error because OE has to first revoke the SELECT privilege from SCOTT.
