Hmm, I wonder if the loop prevention mechanism is a feature or a bug. Maybe OSPF should just embrace the chaos and let the routers duke it out.

This question is making my head spin. I'll just remember to always use area 0 for inter-area communication and hope for the best!

Yes, and an ABR cannot inject Type 3 LSAs back to the same area to prevent loops.

That's a good strategy. It's important to remember that inter-area routes need to be forwarded through area 0.

Wait, so OSPF can have loops between areas? I thought it was a loop-free protocol. What is this sorcery?

I think option D is also true. ABRs can't inject Type 3 LSAs back into the same area, which helps with loop prevention.
