6?
You can use the pythagoras method and it is not given if G is horizontally east of H.
Please correct me if I am wrong.

I would choose 6 too, but I still don't think it makes much sense. I first came up with 164(sqrt).

6 feels like a trap. H-J has to be a hypoteneuse if "due" means directly East and South. SQRT 164 seems like the right answer.

Well, the question is what the CLOSEST to the straight-line distance. The straight-line distance should be 164(sqrt), but it's not among the 5 choices. The CLOSEST to 164 (sqrt) is 13. However, 164(sqrt) should be the shortest distance. 13 is even smaller than the shortest distance. 18 would make more sense, but compared to 13, 18 is not the closest to 164 (sqrt). SO I think the answer should be 13 since it's the closest to 164(sqrt) anyway.
