Greentree: Which code corresponds to Greentree?

Answer: A — Greentree

In this type of map-from-location-to-code question, the correct code is the one that exactly matches the location name. The code for Greentree is Greentree, so that option is the best pick. The other names—Bender, County Line, Mill—refer to different locations and would have their own codes, not Greentree. So Greentree is the only choice that corresponds to Greentree.
