Answer:
B) eliminating tariffs placed on cars imported from the United States
Step-by-step explanation:
NAFTA is a treaty between the United States, Mexico and Canada to create a free market in which tariff barriers and investment restrictions are removed. According to this, options A and D are not valid as the treaty is between the US, Mexico and Canada. Also, option C is not the answer because this treaty would not create quotas as its goal is to eliminate barriers. So, the answer is eliminating tariffs placed on cars imported from the United States.
