I feel like I've seen a question similar to this before, and I remember that the designated port is the one that connects to the LAN, not the greatest distance from it.

I'm not entirely sure, but I remember something about root ports and costs. I thought the root port was the one with the lowest cost to the root, not the highest.

I think option B sounds familiar because we talked about how MAC addresses are used as tie-breakers in the root election process.
