You put your questions in the wrong category, love. You need to move them to physics.
Answer:
The most likely answer would be B) they are enacting protective trade policies
Explanation:
Many countries are trying to protect themselves from the negative consequences that free trade might have on a country. The United States itself is at the very moment negotiating several free trade agreements with the aim of protecting local producers and consumers.
Most economists think that free trade is a good thing, but it is true that free trade can affect some people. Industrial workers and farmers tend to be among those that are usually affected because it can happen that their products become more expensive than imported goods, or in the case of industry, it can move to other countries where wages are lower.
Nationalism usually does provoke violence and rebellions within nations. A great example of such a thing was the assassination of Archduke Franz Ferdinand by a Bosnian Serb due to the fact he was a major Serbian Nationalist and believe Bosnia should be apart of Serbia.

The correct statement is "forbade European intervention in the Western Hemisphere."
The Monroe Doctrine was aimed at separating the world into the Eastern and Western Hemispheres. In this case, the US did not want any European influence in the Western part of the world, especially in the Latin American countries. The US argued that these countries, such as Brazil, Chile, and Bolivia, were under the "sphere of influence" from the US.
Even though the US did not want European countries to interfere with countries in this hemisphere, they had no intention of taking over any colonies established before this doctrine. This meant that the Europeans who already controlled areas in the Western Hemisphere did not have to worry about a US invasion of any sort.
