Which of the following quotations—from documents associated with the American, French and Haitian revolutions—exemplifies social contract theory? a.) "That to secure these rights, Governments are instituted among Men, deriving their just powers from the consent of the governed." b.) “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.” c.) “Liberty consists in the ability to do whatever does not harm another; hence the exercise of the natural rights of each man has no other limits than those which assure to other members of society the enjoyment of the same rights.” d.) “Men are born and remain free and equal in rights. Social distinctions may be based only on common utility.”
