Supporters of nafta and free trade would contend that such agreements
a) increase government control of a nation's economy.
b) limit the growth of an economy and prevents inflation.
c) hamper democratic reforms and open markets in areas that are already strong.
d) stimulate democratic reform and open markets in areas in need of improvement.

Free trade agreements  actually decrease the government's  control of the nation's economy - so a) is not the correct option.

It also strengthens the growth of an economy - so b) and c)  isn't correct either.

 The correct answer is:
D) stimulate democratic reform and open markets in areas in need of improvement.

Free markets stimulate democratic growth!
