It’s A. The LRH is called local because it routes traffic within the local subnet, not just one link. So it covers multiple links in the subnet, which fits better than options C or D.

B tbh, I don’t think it’s about routing or just a local link. The LRH includes LIDs which identify devices within the local subnet, so it’s kind of like an address for local communication. That makes option B make more sense since it’s tied to the subnet's local addressing rather than just a single link or general routing.

Option C sounds right since LRH limits traffic to a local link, not just routing within a subnet. That fits the "local" part better than just subnet routing.

It's about routing within the subnet, so A.
