Which of the following scenarios would be indicative of child neglect?

Failing to provide necessary medical care is a clear example of child neglect. Child neglect occurs when a caregiver fails to meet a child's basic needs, which include adequate nutrition, shelter, supervision, education, and medical care. When a child requires medical attention, it is the responsibility of the caregiver to ensure that such care is provided. Neglect in this context could lead to serious health issues for the child, which underscores the importance of addressing medical needs promptly.

The other scenarios provided, while they involve various forms of parenting and caregiving, do not represent neglect. Setting boundaries is a part of good parenting, encouraging responsibility helps foster independence, and housing a child with a relative for safety demonstrates a caring and protective approach, none of which meet the criteria for neglect.
