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?

impose stricter divisions of labor

increase production quotas

loosen certain trade regulation

permit limited private ventures

Let's look at all the options in turn:
Impose stricter divisions of labor
-this doesn't have anything to do with trade, so it's not the correct answer.

Increase production quotas
-what we want is a bigger trade, not production, so again, not the correct answer

Loosen certain trade regulation
-this is the best answer. Loosening trade regulations will increase trade, but country A won't do it since it would challenge their control over the market

Permit limited private ventures
-in country B those are likely already permitted anyway
