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

What would you suggest to the PL/SQL developers to achieve this?

A. Create the procedure with definer's right.

B. Create the procedure with invoker's right.

C. Grant the EXECUTE privilege with GRANT OPTION on the procedure to selected users.

D. Create the procedure as part of a PL/SQL package and grant the EXECUTE privilege on the package to selected users.
