Which definition best fits the term "delinquent minor"?

The term "delinquent minor" specifically refers to individuals under the age of 18 who engage in behaviors that violate the criminal law. This definition encompasses a range of offenses, including theft, assault, drug offenses, and other criminal activities. The legal system categorizes these actions as delinquent behavior because they are against the law, and the consequences, as well as interventions, are handled differently compared to adults.

While the other options may describe behaviors or issues that minors face—such as being undisciplined in school or having behavioral problems at home—they do not capture the essence of legal violations that define a delinquent minor. The key aspect of the definition is the violation of laws, which is why this particular choice is the most accurate representation of what a delinquent minor is within the context of juvenile justice.
