What are the four main parts of the Declaration of Independence?

The Declaration of Independence is structured into four main parts that collectively articulate the rationale for America's separation from British rule. The correct choice identifies these parts accurately, with the "Opening" serving as the introduction that asserts the purpose of the document. The "Theoretical Core" presents the philosophical foundations of democracy and individual rights, emphasizing principles such as equality and the rights to life, liberty, and the pursuit of happiness.

Following this core, there is the section that provides "Evidence," detailing the grievances against King George III and illustrating the justifications for independence. Finally, the "Conclusion" summarizes the arguments made and formally declares the colonies' intention to separate.

This breakdown not only reflects the logical flow of the document but also captures its essential purpose of justifying a break from British authority through a combination of philosophy and specific grievances, which is central to understanding its significance in American history.
