Assuming static scoping, which declaration of X is the correct one for a reference to X in Sub1, Sub2, and Sub3?

what about with dynamic scoping? meaning you need to point out which declaration of X is the correct one for a reference to X in Sub1, Sub2, and Sub3?

Explain your answer!

procedure Main is X: Integer procedure Sub3: - - This is a declaration of Sub3 It allows Sub1 to call it procedure Sub1 is procedure Sub2 is -- Sub2 is defined within Sub1 X: Integer begin-- of Sub2 end; -of Sub2 begin- of Sub1 end;-of Sub1 procedure Sub3 is begin -of Sub3 end;-of Sub3 begin--of Main end;--of Main Assume that the execution of this program is in the following unit order: Main calls Sub1 Sub1 calls Sub2 Sub2 calls Sub3
