D is the correct answer because you can see in the painting that the columns are in the background, just to provide a nice view.

The US has troops to patrol the demilitarized zone between South Korea and the North. According to Reuters news agency, the American military contingent in South Coere is about 28500 military personnel, who play a mediating role in military confrontations not only between the Koreas, but among the countries in the region, such as China and Japan. In this context, the US military position in Seoul is strategic and must remain even if the Koreas sign a peace treaty.
