Answer:
Correct answer is A.
Explanation:
A is the only correct because longitude measures distance from the the prime meridian to the east and west. As United States are on the west, we know that Wyoming must be on the western hemisphere. At the bottom we see those coordinates, which are leading us to this conclusion.
B is correct as this is not longitude, but latitude.
C is not correct as this is the eastern longitude, therefore it cannot be correct.
