The phrase from The Declaration of Independence suggests that Jefferson was presenting a rational and evidence-based argument against the King, meant to justify the colonies' desire for independence and to demonstrate the injustices they faced. This aligns most closely with option B: "Jefferson knew that the colonists' actions would have an international impact."
He was appealing to the world to show the legitimacy of their claims and actions, indicating an awareness that their struggle for independence would resonate beyond their immediate circumstances. Options A, C, and D do not directly relate to the intent behind the phrase mentioned.
