Which of the following countries is not a part of North America?

North America is a continent entirely within the Northern Hemisphere and almost all within the Western Hemisphere.

North America is the third-largest continent by area, following Asia and Africa, and the fourth by population after Asia, Africa, and Europe. In 2013, its population was estimated at nearly 579 million people in 23 independent states, or about 7.5% of the world's population.

North America was reached by its first human populations during the last glacial period, via crossing the Bering land bridge approximately 40,000 to 17,000 years ago. The pre-Columbian era ended in 1492, with the beginning of the transatlantic migrations of European settlers during the Age of Discovery and the early modern period. However, the first recorded European references to North America (other than Greenland) are around 1000 AD in Norse sagas where it is referred to as Vinland. Present-day cultural and ethnic patterns reflect interactions between European colonists, indigenous peoples, African slaves, immigrants, and the descendants of these groups.

Owing to Europe's colonization of the Americas, most North Americans speak European languages such as English, Spanish or French, and their cultures commonly reflect Western traditions.

Peru is located on the central western coast of South America facing the Pacific Ocean. It lies wholly in the Southern Hemisphere.
