In which one of the following regions are the Andes mountains located?

The Andes mountains are located in South America, forming the world's longest continental mountain range [1][t1]. They stretch for over 7,000 kilometers along the western coast of the continent, passing through seven countries: Venezuela, Colombia, Ecuador, Peru, Bolivia, Chile, and Argentina [t2][t4][t7]. Geologically, the Andes are a continental arc formed by the convergence of the oceanic Nazca Plate and the continental South American Plate [c2]. This tectonic activity resulted in a series of high plateaus and towering peaks, including Mount Aconcagua, which is the highest peak in the range and the highest in the Western Hemisphere [c1][t7]. The range serves as a significant climatic barrier between the Pacific Ocean and the rest of the South American continent [t3]. Unlike the Alps in Europe or the Himalayas in Asia, the Andes are the defining physical feature of the South American western backbone [c1][t1].
