The correct answer is A. To justify US involvement in Latin America

Explanation

The Monroe Doctrine is a doctrine created by US President James Monroe in which he established that any intervention by any European country in America would be taken as an act of aggression that would provoke the intervention of the United States. This doctrine was adopted by President Theodore Roosevelt at the beginning of the 20th century due to the naval blockade that Venezuela was subjected to by European powers. This caused President Theodore Roosevelt to issue the Corollary of 1904 in which he established that the United States government would intervene in any country in which there were rights or properties of Americans to reorganize it in case of being threatened by the actions of European countries, legitimizing colonialism in the Latin American and Caribbean region. According to the above, the correct answer is A. To justify US involvement in Latin America.
