The most accurate response regarding the impact of NAFTA on the economic relationship among the U.S., Mexico, and Canada is:
NAFTA reshaped the economic relationship among the three countries and made them much more enmeshed and interdependent.
NAFTA (North American Free Trade Agreement), implemented in 1994, significantly increased trade and investment between the U.S., Mexico, and Canada. It eliminated tariffs on many goods, reduced trade barriers, and facilitated economic cooperation, leading to greater economic integration and interdependence among the three nations. The other options either misrepresent the effects of NAFTA or do not accurately reflect its role in shaping the economies of the three countries.
