The correct answer is A) It had a complex system of canals, bridges, and dams, with the Great Temple at the center.
The statement that is true of the Aztec capital, Tenochtitlán is "It had a complex system of canals, bridges, and dams, with the Great Temple at the center."
Tenochtitlan was the capital city of the Great Aztec empire in Mesoamerican times. It was located in what today is downtown Mexico City. The city was built over a lake, the Texcoco Lake. That is why they built a complex system of canals, bridges, dams, and chinampas around the main ceremonial center with the two high pyramids to honor Aztec's gods Huitzilopochtli (War) and Tlaloc (Rain).
