CREATE OR REPLACE PROCEDURE create_dept （ v_deptno NUMBER， v_dname VARCHAR2， v_mgr NUMBER， v_loc NUMBER） BEGIN
INSERT INTO hr.departments VALUES （v_deptno， v_dname， v_mgr， v_loc）； END；
The users having permission to execute the procedure are able to insert records into the
DEPARTMENTStable even though they do not have the INSERT privilege on the table. You want only those users whohave privileges on the DEPARTMENTS table to be able to execute the procedure successfully.
What would you suggest to the PL/SQL developers to achieve this（）

B.Create the procedure with invoker’s right.
C.Grant the EXECUTE privilege with GRANT OPTION on the procedure to selected users.
