Which of the following types of cooperatives is formed by small independent producers to sell their output through one centralised agency?

These are voluntary associations of independent producers who want to sell their output at remunerative prices. The output of different members is pooled and sold through a centralised agency to eliminate middlemen. The sale proceeds are distributed among the members in the ratio of their outputs. Marketing societies are set up generally by farmers, artisans and small producers who find it difficult to face competition in the market and to perform necessary marketing functions individually. The National Agricul­tural Cooperative Marketing Federation (NAFED) is an example of marketing cooperative in India.
