The options include:

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
The best reason why the last sentence that is "representatives in the United States had drawn up the Constitution with particular attention to the issue of where they would meet in the future" is due to the behavior of the king.
Since from the passage, we're informed that whenever the Parliament clashed with their monarch, the king would convene the Parliament in an unreachable part of the country and then decide laws as he pleased. This resulted in the change that occured about where they'll meet in the future.
