A

Explanation:

Before domestication of animals, these animals were wild and early humans used to hunt for food. The hunting process  was not always successful and took a lot of energy from the body. Domestication of these animals made food available and other conveniences. An example is cows that emanated from the domestication of wild aurochs. They provided the milk and meat for humans and also labored in the farm in the cultivation of domesticated plants.
