A historical issue,

The correct answer to this question is D.

But if you want to know the meaning of item C, I can give you a brief explanation.

After the victory of the American War of Independence, there was a discussion about the domestic political system. There are two main arguments. The first is to adopt the British constitutional monarchy. Because most people in the United States were British immigrants at that time, they were familiar with this system and were not very exclusive to having a king. The second is to adopt French-style democracy. This option was chosen because France provided great support for American independence, and people like Franklin were grateful to the French. Both options have advantages and disadvantages. On the one hand, Washington refused to be king because he was not interested in being king (this gentleman is very rich, and even the president would not do it if it was not to safeguard the revolutionary achievements). On the other hand, democracy in France is more in line with the present situation in the United States (each state is in an independent state, and a federal or confederate government is established only for foreign affairs and public services). Another reason is also worth noting. No children in Washington inherit the mantle. If he dies as king, the country has no legal heir, and political turmoil may occur again. So Washington's refusal to be king became a matter of course.
