The correct answer is B. Phoenix

Explanation:

The map shows latitude lines (horizontal lines) and longitude lines (vertical lines) in the U.S. Moreover, these lines can be used to locate places by combining a North/South coordinate with a West/East coordinate.

In the case of the coordinates 33°N latitude, 112°W longitude; this shows a place located 33° north, which is between the lines marked as 30°N and 40°N (first and second horizontal line from the bottom of the map). Also, the second coordinate shows the place is located 112° West between the lines marked as 120°W and 110°W (first and second vertical line from left to right). According to this, the city the coordinates refer to is Phoenix because this is the one located at the latitude and longitude of the coordinates.
