What defines an 'abused minor' according to the Juvenile Court Act?

An 'abused minor' as defined by the Juvenile Court Act primarily refers to a minor suffering physical injury from responsible adults. This definition emphasizes the responsibility of adults, such as parents or guardians, to protect the minor and ensure their safety. The presence of physical injury indicates that the minor has been subjected to harmful actions, highlighting the need for intervention by child protective services or law enforcement to address the abuse and safeguard the child's welfare.

The other options touch on different aspects of juvenile challenges but do not specifically align with the legal definition of abuse. For instance, a minor without parental oversight pertains more to neglect, a minor failing to receive necessary education relates to educational neglect, and a minor engaging in delinquent behavior focuses on criminal activities rather than abuse. Each of these scenarios may require intervention but does not meet the specific criteria for an 'abused minor' as outlined in the Juvenile Court Act.
