Which WIC section pertains to a minor at risk from an abusive sibling?

The correct choice relates to the specific section of the Welfare and Institutions Code (WIC) that addresses minors who are at risk of abuse or neglect, specifically from a sibling. Section 300j explicitly pertains to the scenario where a minor is at risk due to emotional or physical harm inflicted by a sibling. This section recognizes that sibling relationships can also lead to significant concerns regarding the safety and well-being of a child, similar to parental or caretaker abuse.

In contrast, the other sections mentioned are designated for different contexts. For example, Section 300i generally deals with minors who may be at risk due to the failure of a responsible caretaker to adequately protect them from significant harm by another child, but it does not specifically target sibling relationships. Section 305 addresses situations where a child may be in danger when they are left without proper care, while Section 602 primarily relates to minors who are involved in delinquent behavior, rather than direct abuse by a sibling.

Thus, Section 300j is the appropriate code for circumstances involving a minor facing risks associated with an abusive sibling, providing clarity and focus on that particular type of familial abuse.
