Which definition best describes pastoralism? a. a part of farming that includes raising animals for food or to sell/trade. b. a part of farming where you specialize in only one crop. c. a part of farming where you only raise cattle.

The correct answer to your question would be A. 

Pastoralism is the branch of agriculture concerned with the raising of livestock. It is animal husbandry: the care, tending and use of animals such as camels, goats, cattle, yaks, llamas, and sheep.

B. isn't correct because the option says only ONE crop, but Pastoralism has to do with agriculture and different kids of plants.

C. isn't the right choice either because it says you only raise cattle and the paragraph above says camels, yaks, and different kind of animals you see in farms. 

Hope this helps!
