Haha, this question is a real head-scratcher! I'm going to have to go with B - R1 and R4 only. It's the most 'out there' answer, so it must be the correct one, right? Just kidding, I think C is the way to go.

I think B is too limiting, C covers more routers.

But routers R2 and R3 are also part of AS 65540, so they should have the BGP update for the advertised prefix.

Hmm, I'm leaning towards D. R1, R4, and R5 seem like the logical choice since they're all directly connected to AS 65541. But I could be overthinking this...

I'm pretty sure the answer is C, only routers R1, R2, R3, and R4 will have the BGP update. The question mentions that AS 65541 is advertising the prefix, and since R1, R2, R3, and R4 are in the same AS, they'll receive the update.
