Suppose that agent A owns one unit while agent B holds no unit. Then, assuming that each agent maximizes his/her gains from trade, 0 A. 1 unit for agent A and 0 unit for agent B is an efficient allocation. 0 B. 1 unit for agent B and 0 unit for agent A is an efficient allocation. 0 C. There is mutually benecial trading between agentA and agent B at a price of 3
