I'm gonna have to go with C on this one. Virtual links are the OSPF equivalent of a video call - they make it seem like areas are directly connected, even when they're not.
Haha, virtual links? More like 'virtual reality' links! But seriously, I think C is the correct answer. It's all about connecting those disconnected areas through the backbone.
I agree with Phuong. Virtual links are all about providing a logical connection to the backbone area when the physical connection is missing. Option B is the winner here.
