      I compile the following package:

      PACKAGE plch_pkg
      IS
         my_flag BOOLEAN := TRUE;
      END;
      
      

      Which of the choices will display "TRUE" after execution?

      Choice 1
      BEGIN
         DBMS_OUTPUT.PUT_LINE (plch_pkg.my_flag);
      END;
      

      Choice 2
      BEGIN
         DBMS_OUTPUT.PUT_LINE (CASE WHEN plch_pkg.my_flag THEN 'TRUE' END);
      END;
      

      Choice 3
      BEGIN
         DBMS_OUTPUT.PUT_LINE (CASE WHEN plch_pkg.my_flag THEN 'FALSE' END);
      END;
