A retail cooperative society is an organization that is formed by a group of individuals with the aim of pooling their resources together to purchase goods and services in bulk for their mutual benefit.
The answer is likely option (B): cutting off the profit of middlemen. By purchasing goods in bulk, the retail cooperative society is able to negotiate lower prices from manufacturers and suppliers, and then sell these goods directly to their members at a lower price than what they would have paid through middlemen, thus cutting off the profit of middlemen. This helps members save money and obtain quality products at a lower cost.
While the other options may be benefits or activities of a retail cooperative society, the main aim is to provide members with goods and services at a lower cost through collective purchasing power. Therefore, option (B) is the most likely answer.
