Which constitutional right allows citizens to assemble peacefully?

The right that allows citizens to assemble peacefully is grounded in the Freedom of Assembly. This right is enshrined in the First Amendment of the U.S. Constitution, which guarantees that individuals can gather for collective purposes, such as protests, demonstrations, or other forms of expression, as long as they do so peacefully. This constitutional protection is vital for allowing citizens to express their views collectively and to advocate for changes within their communities or at a national level.

Freedom of expression, while related to the ability to share ideas and opinions, specifically focuses on speech and writings rather than the act of gathering. Similarly, freedom of religion pertains to the practice of faith and spiritual gathering, not general assembly for dialogue or protest. The right to a trial by jury addresses legal proceedings and does not pertain to the gathering of individuals in a public or private space. Thus, the distinct terminology and focus of "Freedom of Assembly" specifically highlight the allowance for peaceful gatherings, making it the correct answer in this context.
