The right option is; C. constructed advanced irrigation systems

From about 1000 – 1400 CE, the Pueblo people constructed advanced irrigation systems.

The Puebloan people were an ancient Native American culture that extended across the four regions of the United States. The Puebloan people consist of three main groups which were the Mogollon, Hohokam, and Anasazi. From about 1000 – 1400 CE, the ancestral Puebloan people constructed advanced irrigation systems which allowed the Pueblos to start planting beans and squash, in addition to corn that they were planting before. The complex irrigation systems allowed the growth of agriculture which produced new forms of production and societal development.

it is very hard for the climatologists to precisely predict how will the global temperatures be changing so there's lots of models, some of which differ significantly, this is due to multiple factors, and probably the most important is the human activity.

humans have been a key factor in climate change around the globe since the start of the industrial revolution, and in the past few decades the consequences are becoming more obvious. there's lots of emission of pollutants in the atmosphere as well as changing the environment on the surface itself, so it's really hard to predict how will that go in the future because there's some countries that are reducing the damage and are going towards green energy, while others are stubbornly continuing with pollution and damages to the environment.
