Answer:
Key words I noticed in the question were "President Obama", "justifying to Congress", and the statement "No system of government can or should be imposed by one nation by any other."
My answer is D. conflict resolution within a country between a president and a military dictator because President Obama would likely justify to Congress the need for conflict resolution within a country where there is a dispute between a president and a military dictator. This aligns with the statement that governments should reflect the will of the people, and conflict resolution in such situations can help ensure that the government represents the people's interests.
I eliminated answer A. Developing an alliance with a newly selected oligarch because it goes against the statement that no system of government should be imposed by one nation on another. Developing an alliance with an oligarch may involve imposing a certain system of government on a nation, which may not align with the principle mentioned in the statement.
I eliminated answer B. Conflict resolution between a dictator and a monarch because it also involves resolving conflicts between two individuals who hold positions of power, which may not necessarily reflect the will of the people or align with the statement.
I eliminated answer C. Diplomatic alliances with a newly prime ministers because it mentions diplomatic alliances, which may not necessarily involve conflict resolution within a country or reflect the will of the people. It does not directly align with the statement mentioned in the prompt.
