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

The Declaration of Independence, adopted on July 4, 1776, articulates certain unalienable rights that are considered fundamental to human existence. Among these, the right to "life, liberty, and the pursuit of happiness" is explicitly stated in the document. This phrase captures the core belief that individuals are entitled to live freely, have their rights to life protected, and pursue their own happiness as they define it, a principle rooted in Enlightenment philosophy.

Other options presented are significant rights but are not included in the Declaration of Independence. For example, freedom of speech is a component of the First Amendment of the United States Constitution, the right to bear arms is outlined in the Second Amendment, and voting rights are addressed in various amendments to the Constitution, including the Fifteenth and Nineteenth Amendments. While these rights play critical roles in American democracy and civil liberties, they do not derive directly from the Declaration of Independence, making "life and the pursuit of happiness" the correct response in this context.
