• B.

Generate 90% of their income from the sale of livestock

• C.

Doublecrop

• E.

Circumvent market forces that determine the prices of livestock and crops

C. Doublecrop
Explanation
Mixing crops and livestock allows farmers to doublecrop, which means they can grow two different crops in the same field in a single growing season. This maximizes the use of the land and resources, increasing productivity and profitability. By integrating crops and livestock, farmers can also create a system where crops provide food for the livestock, while the livestock provide manure for crop fertilization. This symbiotic relationship enhances soil fertility, reduces the need for external fertilizers, and promotes sustainable agriculture practices.
