Answer: The correct answer is: Enlightenment thinkers believed people had unalienable rights.
Explanation: The passage from the Declaration of Independence reflects Enlightenment thinking by asserting that all people have unalienable rights that are endowed by their Creator, such as Life, Liberty, and the pursuit of Happiness. This idea of natural or inherent rights was a central belief of Enlightenment thinkers, who emphasized reason, individualism, and the importance of individual liberty and human dignity.
