Apositive result of trade agreements such as nafta and the eu is
a. fewer sanctions against developing economies.
b. more economic rights for citizens.
c. more support for domestic companies.
d. fewer competitors in the global economy.

The correct answer is D.

NAFTA and EU are free trade zones. Member nations can freely trade inside because trade barriers among them had been removed, while they still enforceable against third parties (countries that do not pertain to the free trade area).

Therefore, when conducting transactions inside, firms from the member states experience less competition, because foreign international rivals do not compete in equal terms, as they have to face trade barriers if they want to do business in the region. Many of these foreign competitors are not able to compete under such conditions and therefore domestic producers face fewer competitors.
