It's hard to pick the second on. I would say that your best choice is the second one. Sometimes as in Brazil, people generally accepted a monarch as ruler. Brazil is kind of an odd case though. They proclaimed their independence and then set up their own monarch. So 2 and 3 I don't think are answers.

Monroe was always, during his Presidency, very concerned about the colonization of states in South America. He had definate views on what should be done. His basic principle was "Hands off. America is for Americans." These remarks were not limited to the defense of the United States. He meant North and South America. The quotation you want, I think, is
...<em> by the free and independent condition which they have assumed and maintain are henceforth not to be considered as subjects for future by any European powers.</em>
