Country A has an absolute command economy. Country B has a mixed economy and a population that favors market trade. Both want to increase trade to generate more wealth. Which action would Country B most likely take that Country A would not?

D) permit limited private ventures

Explanation:

In a command economy the government decides how to allocate resources, and they generally do not do it very well.

In a mixed economy that favors free markets, the market (suppliers and consumers) can decide how to allocate resources, at least in a limited way. So country B would probably be willing to allow private companies, even foreign private companies, to start trading (exporting and importing goods).
