Which of the following is considered a felony?

Robbery is classified as a felony because it involves the unlawful taking of property from a person through force or intimidation, which poses a significant threat to the safety and well-being of individuals. Felonies are typically serious crimes that carry severe penalties, including lengthy prison sentences or substantial fines. The nature of robbery, which can lead to physical harm and emotional trauma for victims, elevates it to this level of offense in legal terms.

In contrast, traffic violations are generally categorized as misdemeanors or infractions unless they result in serious injury or significant repeat offenses. Public intoxication is also typically treated as a misdemeanor, as it does not usually involve direct harm to others or violence. Disturbing the peace, while potentially disruptive, is usually classified as a misdemeanor as well. These classifications reflect the legal system's approach to distinguishing between varying degrees of criminal behavior based on their severity and impact on society.
