The correct answer is "A".
The Roosevelt Corollary is an addition to the Monroe Doctrine of 1823, which granted the newly formed Latin American Democracies protection against further European attempts to regain their territories.
Roosevelt's proposal, which was passed in 1904, issued that the United States will intervene in conflicts between the European Countries and the Latin American Countries to enforce "legitimate claims" of the latter group. This would be seen as the consolidation of US Economic interests in the Latin American region, as it not only would repeal military European Attempts but also intervene in further economic affairs.
