I am not looking at the lab at the moment, but if memory serves.
Charlie is a normal area.
So him receiving routes from router A/B are fine.
You will only see a difference in the routing table on routers inside a stub area.
So router A in this Lab.
In a stub area, with no summary routes allowed, there should only be a default route on how to get out of the area.
But the ABR will send out the information it receives from the stub area to the backbone area and to other areas.
So B is the ABR in this case.
