Answer 1

The significance of the Monroe Doctrine is best captured by option D: it opposed European involvement in the Americas. The Monroe Doctrine, articulated in 1823, was a key U.S. policy that warned European nations against further colonization and interference in the Americas, asserting that such actions would be seen as acts of aggression. It was significant in shaping U.S. foreign policy and establishing the Americas as a sphere of influence for the United States.
