What major structure is associated with Teotihuacan?

The correct answer is the Pyramid of the Sun, which is a significant structure located in Teotihuacan, an ancient Mesoamerican city in present-day Mexico. The Pyramid of the Sun is one of the largest pyramids in the world and represents a key feature of Teotihuacan's monumental architecture. It was likely constructed during the early periods of the city’s development, around 100 CE, and played an essential role in the city's cultural and religious practices.

The Pyramid of the Sun is important not only for its size but also for its orientation and the rituals that may have been performed there.
