Which of the following rights is listed in the Declaration of Independence?

The Declaration of Independence clearly articulates certain inalienable rights that are foundational to the principles of democracy in America. Among these rights, the phrase "life, liberty, and the pursuit of happiness" is prominently featured. This expression embodies the Enlightenment ideas of individual rights and government’s role in protecting those rights. The framers of the Declaration, particularly Thomas Jefferson, believed that these rights are inherent and cannot be surrendered or taken away, making them essential to the identity of the nation.

In the context of the other choices, freedom of speech and the right to bear arms are not explicitly mentioned in the Declaration of Independence; they are addressed in the Bill of Rights, which was ratified later as part of the Constitution. The right to a speedy trial, similarly, is also found in the Bill of Rights and is not part of the Declaration. Therefore, the correct answer emphasizes the foundational concept of individual rights as stated in the Declaration of Independence.
