I'm not sure about option B, routers discarding valid but inaccurate information from neighbors doesn't sound right to me. I think option D is correct because routers relay information delivered by neighbors.
I agree with Anna, routers do advertise information about themselves. I also think option A is correct because routers summarize information they learn from neighbors.
