Which of the following is not an archaeological site located in Mexico?

Machu Picchu is not located in Mexico; it is an iconic archaeological site in Peru. Recognized for its stunning Inca architecture and historical significance, it stands high in the Andes Mountains. In contrast, Teotihuacan, Chichen Itza, and Monte Alban are all located in Mexico. Teotihuacan is famous for its monumental pyramids and ancient urban planning, Chichen Itza is renowned for the Temple of Kukulkan and other Mayan ruins, and Monte Alban features significant Olmec and Zapotec relics. Thus, identifying Machu Picchu as the outlier underscores its geographical distinction from the other sites that have rich histories rooted in Mexican culture.
