The correct answer is C. John Locke.
John Locke wrote a famous book, called Two Treatises of Government, in which he explains his philosophies on how governments should be structured. In this book, he discusses several different ideas such as the concept of natural rights, the ability of citizens to overthrow a tyrannical government, and how the source of government power lies in its citizens. All three of these ideas are implemented into the US Declaration of Independence which was written by Thomas Jefferson.
