The correct answer is: "(T)hey are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness."
Explanation:
John Locke (1632 - 1704), as well as other philosphers of his time, highly believed in the existence of natural rights, those rights that are part of beings given to them by nature itself, and not by the existence of laws. These natural rights, are almost born with human beings, and they cannot be changed, touched, removed, or altered in any way by laws, governments, or others. No rights, Locke believed, came above these natural rights, and all laws were created as a means to ensure and protect these natural laws. To Locke, these natural laws were: Life, Liberty and Estate. Some historians say that the natural law of Pursuit of Happiness came from Thomas Jefferson, and not from Locke himself, as it was Jefferson who first used this term in the Declaration of Independence, not Locke.
