Android : Handling back press in nested fragment android

I am working with nested fragment and I am facing issue when I press back.

Flow:

FragementActivity

A(Fragment)     B(Fragment)

 C      D        E     F

This is a structur of my application. Where C,D,E,F is child fragments and not added in back stack. D contains List fragment, and from D I called B. But When I press back from B I want again D with last selected position. I added A and B in back stack. How can I achieve this. Provide me some solutions. I recalled D but the selected position changed always.
