The correct answer is: "no barriers to trade from nation to nation"
When two countries or a group of countries become members of a common market, trade barriers such as tariffs or quotas are eliminated between the participats. For example, this is the situation established by the NAFTA agreement signed by US, Canada and Mexico to create common markets for many products, hence, to remove trade barriers in those markets. Countries that constitute the European Union also are members of a common market.
