Answer: A. He used Enlightenment principles to help explain why the United States was demanding its independence
Explanation:
Although his work would go through a process of revision by other committee members and the Second Continental Congress, Thomas Jefferson is deemed the main writer of the Declaration of Independence.
He used Enlightenment ideas, such as those of John Locke about "life, liberty, and property" being natural rights, to draft the Declaration of Independence. However, Jefferson wrote about natural rights being "life, liberty, and the pursuit of happiness".
