Final answer:
The correct answer is option A. Monroe Doctrine.
Step-by-step explanation:
The speech is most associated with the Monroe Doctrine. In 1823, President James Monroe outlined this principle of U.S. foreign policy, which warned European nations against interfering with independent countries in the Western Hemisphere. It stated that any interposition for the purpose of oppressing or controlling the destiny of the newly independent governments in Latin America would be seen as unfriendly and hostile towards the United States.
The Monroe Doctrine aimed to establish the Western Hemisphere as the United States' area of interest and assert its stance against European colonization and intervention in the region.
