Unfortunately, you forgot to include the options for this question.
However, doing some research, we can answer the following.
The event that happened first in the founding of the United States is "England's North American colonies protested England's laws and taxes."
That is true because the American colonists were upset and angry due to the many and high taxes imposed by the English government. We are talking about the Navigation Acts, the Stamp Act, The Tea Act, or the Townshend Acts.
The worst part of it was that the colonies had to pay these high taxes but they did not have a voice in the British Parliament. Of course, this was a major cause for the beginning of the Revolutionary War of Independence.
