Which of the following is excluded from being classified as delinquent?

The correct choice is that both a civil infraction and a first offense misdemeanor are excluded from being classified as delinquent.

In the context of juvenile law, delinquency typically refers to a minor committing an act that would be considered a crime if committed by an adult. However, not all legal infractions or offenses fall into this category. A civil infraction is generally regarded as a non-criminal violation, which means it does not carry the same legal consequences as a criminal act. This includes minor offenses such as failing to wear a seatbelt or a noise complaint, which do not result in criminal charges or delinquency status.

Additionally, a first offense misdemeanor often falls under diversion programs or similar options that aim to rehabilitate rather than punish. Many jurisdictions provide mechanisms to keep first-time offenders from being labeled as delinquent if they satisfy certain conditions, such as completing educational programs or community service.

In summary, both civil infractions and certain first-time misdemeanors do not meet the criteria for classification as delinquent acts, which contributes to the correct answer indicating their exclusion from delinquent status.
