B. the use of flood plains and irrigation

C. the industrialization and mechanization of farming

D. a change in climate that made foraging impractical

 ANSWER

The correct option is B.

Before the emergence of agricultural settlement, people move about from one place to another, looking for food for themselves and their families. The shift from hunter gathering to agricultural settlement occurred when these people found suitable conditions that allowed them to settle down in one place with their families and cultivate their own foods. The use of flood plains and irrigation made available for them the water necessary for the growth of their crops.
