Hmm, the sequence number is lower, so the router shouldn't update its LSDB. I think option B is the right choice here.

I believe the correct answer is C) The router updates the information in its LSDB with the information received from its neighbor. It makes sense to keep the LSDB up to date.

I agree with Freida. The router should update its LSDB to reflect the most recent information.
