Which of the following regions is located east of North America?

The correct answer focuses on the geographical positioning of Europe in relation to North America. When looking at a map, Europe is situated directly to the east of North America, separated by the Atlantic Ocean. This proximity has facilitated various historical connections, cultural exchanges, and trade routes between the two continents.

In contrast, Asia lies much further east from North America, but it is not the region immediately adjacent to it. The Arctic Circle is a polar region encompassing parts of several countries and is positioned to the north rather than the east. South America, meanwhile, is located to the south of North America, thus making Europe the only region listed that is directly to the east.
