First, let us understand what a farm cooperative is and its purpose. A farm cooperative, or farmers union, is an organization or movement created by members that belong to a part of society or an economical activity, such as agriculture, to ensure their rights, protect their members and help their members improve. In the United States, and all over the world as well, especially during the end of the ninteenth and most of the twentieth centuries, people who belonged to different sectors of the economies would band together to improve their possibility for success in their business, especially given the difficult times people were facing. Such was the case of the agricultural alliances that were created in the U.S particularly during the 1800´s .
Although it is also important to understand that most of the options are examples of agricultural organizations that sought to improve the life and wellbeing of farmers in the United States during the 1800´s, and that the Farmers´ Alliance became the biggest movement of farmers to help each other, the perfect example of a farm cooperative is actually the National Grange, given that they were not just a political movement with political intents, but they actually became a group of farmers, founded by Oliver Hudson Kelley who sought to ensure the empowerment of farmers and form them into groups, or granges, that worked together to ensure better conditions for their people. This is why the correct answer would be A.
