c) Adams-Onis Treaty

d) Rush-Begot Treaty

Answer: Monroe Doctrine

The correct answer is (A): Monroe Doctrine. It is basically a policy statement made by former President James Monroe in the year 1823.

The Monroe Doctrine became an important part of American foreign policy for 170 years. It states that any European attempts to colonize or interfere in the affairs of the newly independent nations of Latin America would be viewed as acts of aggression requiring U.S. intervention.

Based on three principles, the Monroe Doctrine declared that the western hemisphere is no longer open for European colonies, the US would oppose the European powers interfering in their affairs, and the US will not interfere in European affairs.

Overall, the Monroe Doctrine set the stage for American foreign policy for many years to come, shaping how the US interacted with other nations in the Western Hemisphere.
