C. They have less economic reliance on other countries.

D. They are safe from economic competition with other countries.

The correct answer is B. They have fewer barriers to trade than they do with other  countries.

B is the correct answer because in the trade bloc unions countries are able to trade with lower taxes, without physical boundaries. For example European Union is also trade union, which allows people and goods to be transport without any type of boundaries.
