The answer is d. it identified and focused on principles and issues that would unify the various colonial groups.

The Declaration of Independence was kind of like a "break up letter" between the original colonies and King George along with the rest of the British Monarchy. Thomas Jefferson wrote the Declaration of Independence to give King George a list of reasons the colonies would no long accept British rule. Each reason is referred to as a grievance. These grievances served as a guidelines for the government and society the colonies didn't want and in turn, shaped the principles and issues that would unite the colonies to become the United States.

For example, the fifth grievance states that "He has made Judges depend on his Will alone, for the tenure of their offices, and the amount and payment of their salaries." What this means is that the judges were being unfair to the colonists and convicting them based on what was in the best interest of the King, because he had the power over their careers and salaries. This grievance paves the way to unite the colonies in their common principle of trial by jury. Later, the sixth amendment to The Bill of Rights will require that all people suspected of a crime will have a trial in front of a jury of their peers. So, the fifth grievance transpires to the sixth amendment and is an example of how the Declaration of Independence united the colonies with common principles.
