hi,
Answer B is correct as the "O IA" means Inter Area OSPF route --> route learned within the same area.

Hi Mahmoud,
AFAIK O IA are inter area routes which are originated from other areas and O are intra area routes which are generated from within area.
I believe answer B is correct because 6.0.0.0/8 is learned from neighbor which is within the area and I believe its learned via 5.x.x.x which may be its neighbor and may be in same area.

Hi Ankur,
You are absolutely right "O IA" means Inter Area not Intra Area, i truly apologies for this newbie mistake :), and i think that your explaination is definitely right.

Hi Ankur,
thanks a lot for your answer.any way, it seems that B is the correct answer even though it not clear that 5.x.x.x is within the area.
