You are debugging a form with three program units: PU1 calls PU2, which in turn class PU3. While running the form in debug mode, what action can you perform in Forms Builder to change the execution order so that PU3 executes before PU2?
A.
When PU2 and PU3 are both in the Stack panel, drag PU3 to a position above PU2 in the stack.
B.
Open all three program units in the Stack panel and drag PU3 so that it is positioned between PU1 and PU2.
C.
Open the PL/SQL Editor and change the code for PU1 so that it calls PU3 instead of PU2.
D.
You cannot change the execution order while the form is running in debug mode.
