Final answer:
option C. Pastoral societies began in Central Asia because the region had dry climates that were not well suited for agriculture.
Step-by-step explanation:
Pastoral societies began in Central Asia largely because of the dry climates that were not well suited for agriculture, indicated by option C. In areas with limited rainfall and less fertile soil, it was difficult for crops to thrive. However, these regions had an abundance of grasslands, which made it ideal for herding animals as a means of survival. By relying on large herds of animals for food, pastoral societies were able to adapt and flourish in these arid environments.
