The FALSE statement about the Monroe Doctrine is:
D. It declared war against Britain, resulting in the War of 1812.
The Monroe Doctrine was a policy established in 1823 that asserted that the Western Hemisphere was under the influence of the United States and warned European nations against further colonization or interference in the Americas. It did not declare war against Britain; rather, the War of 1812 was primarily fueled by maritime issues and trade restrictions between the United States and Britain, and occurred before the Monroe Doctrine was articulated.
