Question

Answer 1

From my read of the source code, it appears that the implementations of FragmentManager and Activity only work with the root FragmentManager for adding to the options menu/action bar, not and child FragmentManager instances.

Fragment B presumably will need to manage the options menu/action bar on behalf of the contents of the ViewPager, changing what is in the options menu/action bar based upon the pages being shown and hidden in the pager.
