Answer:
The correct answer is B. The doctrine of noncolonization in the Monroe Doctrine was a response to the aparrent designs of the Russians in Alaska and Oregon.
Step-by-step explanation:
The Monroe Doctrine was a principle in the foreign policy of the United States during the 19th century. The term is derived from a speech that American President James Monroe gave in 1823 to Congress. Monroe declared that any form of European involvement in the Western Hemisphere would be considered an attack to US interests. However, Monroe promised to respect the existing colonies in the hands of the European powers.
With the ban on intervention, Monroe also hoped to stop a possible European attempt to sabotage the American expansion process. The British, the Spaniards and the Russians in particular were watched with suspicion, because they had adjacent territories on the continent. In addition, many colonies in South America had successfully fought their independence, after which they soon gained diplomatic recognition from the United States.
