The correct answer is B, that the U.S. Was in charge of the Western Hemisphere.

The Roosevelt Corollary was an extension of a previous idea to the Monroe doctrine. On the one hand, the main idea of Monroe's doctrine was to prevent European's intervention in the Western Hemisphere, on the other hand, Roosevelt corollary was used to justify America's invention throughout the Hemisphere. President Roosevelt issued his Corollary to ensure financial strength and to keep other powers outside the Hemisphere. Therefore he announced his message to Congress in December 1904 and declared itself the In-charge of the Western Hemisphere.
