Which of the following exchange rates for one unit of cloth would be mutually beneficial, allowing for a gainful trade for both Producer A and Producer B?

Defining the Zone of Mutually Beneficial Trade

Producer A can produce 10 computers or 20 cars per month. Producer B can produce 15 computers or 45 cars per month. For trade to occur, they must agree on an exchange rate. Match each potential exchange rate below to its correct outcome.
