Because many people think different things about how they should others which is why sometimes it could be legal and other times it could be illegal.
I would say the best answer to this question would be option C "unelected head of state." Just because monarchy is like a kingdom and the throne can be handed down to anyone who doesn't have to be elected. It isn't none of the other options because the United States has a democracy and also has a constitution, political parties, and representatives who make laws. While monarchy is ran by a king.
Hope this helps.
