Step-by-step explanation
The Declaration of Independence was a document in which the thirteen colonies declared themselves independent from the Kingdom of Great Britain. This statement was made by various intellectuals (including Thomas Jefferson) who drew on the ideas of the Enlightenment and the principles of liberty, equality, and the pursuit of liberty. In the second paragraph, Jefferson establishes the main ideological premises of the Declaration of Independence such as "We hold these truths to be self-evident, that all men... are endowed by their Creator with certain unalienable rights, that among these are life, liberty, and the pursuit of happiness". So the correct answer is B.
