The correct response regarding the influence of John Locke on the Declaration of Independence is: It is based on the concept of natural rights and social contract theory.
John Locke’s philosophy heavily influenced the Enlightenment thinking that shaped the Declaration. He argued that individuals have natural rights to life, liberty, and property, and that governments are formed through a social contract to protect these rights. If a government fails to do so, citizens have the right to overthrow it. This idea is reflected in the Declaration’s assertion of the right to "life, liberty, and the pursuit of happiness," as well as in the justification for declaring independence from King George III.
While the document does list grievances against the King and touches upon ideas related to the Rights of Englishmen and the structure of government, the foundational influence of Locke is primarily in the realms of natural rights and the social contract.
