The statement that BEST describes how and why unruly behaviors are treated differently than delinquent behaviors in the juvenile justice system is:
B) Unruly behaviors result in milder consequences because the activities are not crimes if adults commit them so the court focuses on support and rehabilitation.
This option accurately reflects the distinction between unruly behaviors (which are often non-criminal acts that are considered problematic, such as skipping school or curfew violations) and delinquent behaviors (which are criminal acts that would also be considered crimes if committed by adults). The juvenile justice system often aims to address unruly behaviors with a focus on rehabilitation rather than punishment, as they are not deemed serious crimes.
