Nested navigation controllers and back button

I have a simple question regarding Navigation Controllers and how the back button works.

I have a storyboard as follows:

Navigation Controller --> 
        (A)TableController --click on cell--> 
                (B)TabBarController (2 tabs) -->
                      Navigation Controller --> 
                                (C)TableController -->
                                     (D)TableController.

My problem is that when i click on the back button at (D) it goes back to point (A).

I want D to go back to C - i.e make the back buttons go back to the previous screen and not what seems to be the root (A).

Thanks
