Which right allows individuals to assemble peacefully?

The right that allows individuals to assemble peacefully is the right to assemble. This right is enshrined in the First Amendment of the United States Constitution, which guarantees the freedom of assembly as a vital aspect of democratic expression. This provision enables people to gather, protest, and advocate for their beliefs or causes without interference from the government, as long as their assembly is peaceful.

In contrast, the other options do not pertain to the specific right of peaceful assembly. The right to vote focuses on the participatory aspect of democracy, allowing citizens to choose their representatives and influence legislation. The right to a fair trial pertains to legal proceedings and ensuring justice is served within the judicial system. The right to bear arms is related to gun ownership and self-defense rights. Each of these rights serves important functions in society, but only the right to assemble directly addresses the ability of individuals to come together peacefully for collective action or expression.
