The correct answer is - B. political.
The United States had always had a big interest in the Latin American region, and this mostly because of economic and political reasons. The region is bordering the United States, so it is essential for them to have nice relations with them, or as the United States do, to have control over them. Since the United States import a lot of goods from Latin America, it is of great economic interest for them to have control over the region. Also, since big portion of the Latin American countries have been on the verge of becoming communist countries in the past, the United States didn't wanted to have another Cuba in the area, so they put a lot of effort and got heavily involved in the political affairs of this countries, in order to control the situation.
