Question

Which passage from the Declaration of Independence reflects the enlightenment principle of popular sovereignty

Answer 1

Here is the passage from the Declaration of Independence that expresses popular sovereignty.  I've underlined the most notable line in that regard.

• We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness. — That to secure these rights, Governments are instituted among Men, deriving their just powers from the consent of the governed, — That whenever any Form of Government becomes destructive of these ends, it is the Right of the People to alter or to abolish it, and to institute new Government, laying its foundation on such principles and organizing its powers in such form, as to them shall seem most likely to effect their Safety and Happiness.

"Popular sovereignty" means the people are in charge of establishing a government over themselves.  The founding fathers of the United States adopted the idea of popular sovereignty from Enlightenment philosophers like John Locke (of England) and Jean-Jacques Rousseau (of France).
