The correct answer is letter "C": refers to a situation where a government does not attempt to influence through quotas or duties what its citizens can buy from other countries.
Step-by-step explanation:
Free trade is an agreement between countries to tear down the barriers that impede the free flow of products and services among their territories. This pact implies reducing or eliminating tariffs and quotas between those countries to facilitate trade.
An example of a free trade zone is the North American Free Trade Agreement (NAFTA) signed by Mexico, the U.S., and Canada by which those countries organize their efforts to create a zero-tariff trading block setting standards for the operations of their companies and allowing products manufactured by the three countries to be inexpensive among those territories.
