The following questions someone determine what type of economy a country has expect a) what to produce b) for whom to produce c) how to produce d) what is the price

The correct answer is C) How to produce

No matter what economic system you are talking about, all of them include information on what to produce, who to produce it for, and what the price is. For example, in a free market economic system (like the one used in the US), businesses decide what to produce and who to produce it for. The price is then determined by competition among businesses. However, there is no reference as to how these products should be made.
