Answer: A) Domesticated animals raised for agricultural purposes, such as meat, milk, or wool.
Explanation: The term livestock is usually used to refer to domesticated animals, but not domesticated plants or livestock. Thus, choice C is not a suitable answer choice. In addition, livestock refers to domesticated animals that are kept for their resources, such as milk, wool, meat, or physical labor. Thus, pets do not fit the description of livestock, and thus choice D is also incorrect.
Since livestock refers to creatures that have been domesticated by humans, choice b is incorrect. After all, it is nearly impossible to keep wild animals in enclosures and harvest them for resources. Livestock specifically refers to human-domesticated animals that live on human lands/structures.
