Come on, please quick

Read the passage from The American Plague. Whenever the Parliament clashed with their monarch, the king would get his way by suddenly convening Parliament in a remote, unreachable part of the country. Without a proper quorum of members, the king could then decide law as he pleased. As a result, representatives in the United States had drawn up the Constitution with particular attention to the issue of where they would meet in the future. The best reason why the last sentence is an effect is because it defines an event that created the king’s official behavior. a change that occurred due to the king’s behavior. a relationship that occurred due to the king’s behavior. a central idea that led to a change in the king’s behavior.
