The correct answer is C) developing of irrigation methods.
One characteristic of the Aztec Empire was the developing of irrigation methods.
The Aztec Empire was a dominant tribe in Mesoamerica in the 1500s. Mesoamerica is the vast region from the center of Mexico until the region of Oaxaca and part of Tabasco states. The Aztec people were fierce warriors that conquered other tribes such as the “Tlaxcaltecas” and the “Cholultecas”. The Aztecs developed irrigation methods, as well as constructed floating gardens called “Chinampas” that still today are used in the suburb of Xochimilco, southside Mexico City.
