Which of the following best defines a dependent juvenile?

A dependent juvenile is defined as a child who lacks proper parental care and guidance, typically due to circumstances such as abandonment, abuse, or neglect. This definition aligns closely with the option stating that a dependent juvenile is one without a parent or proper guidance. This scenario indicates a situation where the juvenile does not have the necessary support or supervision from a parent or guardian, which is critical for their well-being and development.

The context of dependency often involves legal systems stepping in to ensure that the child's needs are met, which can lead to alternative living arrangements such as foster care or involvement in social services. In this regard, identifying a juvenile as dependent is focused on the lack of appropriate adult care rather than the specific living conditions or oversight by the legal system.

While options referencing living in foster care and legal supervision might suggest circumstances often associated with dependent juveniles, they do not directly define the term. The core concept of dependency is rooted in the absence of parental guidance or care, making the definition that emphasizes lacking a parent or proper guidance the most accurate choice.
