Answer:
The correct answer is A) Irrigation of crops
Step-by-step explanation:
It is a very imprecise question.
Irrigation canals were built in sedentary indigenous settlements and the best example (if not the only one) is that of the Hohokam tribe, desert farmers who occupied the heart of Arizona and the northern part of Sonora in Mexico from the beginning of the first millennium to Almost in the middle of the second millennium. But it is an isolated case. The expansion of cultivation systems with artificial irrigation was due to the settlements of Spanish settlers in California, New Mexico, Texas and Arizona.
