Which of the following describes a riot?

A riot is specifically defined as unlawful violence involving three or more individuals. The key element in this definition is the presence of unlawful violence that disturbs public peace. While the option that states "unlawful violence by twelve or more individuals" may suggest a larger scale disturbance, it does not align with the standard legal definition of a riot, which hinges on the minimum involvement of three people engaging in violent acts.

The option describing a peaceful protest is inaccurate because a riot, by definition, implies violence and disorder, contrasting significantly with a peaceful assembly. Similarly, a legal assembly with aggressive behavior does not meet the criteria of a riot; even if aggressive behavior is involved, if the assembly is legal, it does not constitute unlawful violence necessary for a riot designation. Therefore, identifying unlawful violence by three or more individuals as a riot connects directly with the legal framework that addresses public order offenses.
