6. I believe it is A. Factors of the Creation of the Monroe Doctrine., especially in the long run.
The Monroe Doctrine was created during the presidency of James Monroe, who was office from 1817 - 1825. You must remember that the Louisiana Territory was under French rule, Florida, and south-western parts of the United States was under Spanish rule, and other European countries claiming smaller territories within the current US. However, with the purchase of the Louisiana Purchase as well as the Gadsden Purchase and the Acquisition from both the Texas Independence (in which Texas joins the Union), and the Mexican-American War, the US gained large amounts of territory at once, as well as large amounts of population. The Monroe Doctrine was an ultimatum to European countries, in which the US was the regional power, and that it would use it's resources to "protect" it's neighbors and it's own interests. In this case, the European countries were not to interfere with territories in the US, creating the U.S. sphere of influence. However, existing colonial powers were not removed by the U.S.

This fits the concept of Manifest Destiny perfectly as Manifest Destiny was the US desire to expand westward across the North American territory. Purchasing the Louisiana territory allowed the US to expand westward and explore new territory while spreading American people and culture.
