Wait, so BGP Fast Reroute is triggered by IGP events? That's kind of counterintuitive, isn't it?

D is definitely false. BGP Fast Reroute wouldn't use the optimal path, it would use a pre-computed backup path.

I'm leaning towards B as the correct answer. The backup path being pre-computed makes a lot of sense for fast rerouting.
