What is a major benefit for countries that join a trade bloc? A. They are given free access to natural resources owned by other
countries.

B. They have fewer barriers to trade than they do with other
countries.

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.

Explanation:

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.

A is wrong because being in a trade union doesn't give you the right to use the natural resources of other countries. It only allows you to easier trade with them.

C is also wrong because in this case they not to rely a lot to the countries that are in that bloc.

D is partially correct, but it also depends on how wide and strong the bloc is.
