Which of the following is an indicator that a child has been neglected?

A child's unhealthy and dirty appearance is a significant indicator of neglect. When a child consistently appears unkempt, it often points to a lack of basic care and supervision, which includes not receiving proper hygiene, nutritious food, and adequate clothing suitable for the environment. This kind of neglect can have serious short- and long-term effects on a child's physical and emotional well-being.

Frequent hospital visits, while concerning, may not solely indicate neglect; they could stem from various medical conditions or accidents that do not reflect a child's overall care situation. High academic achievement and social engagement typically suggest that a child is receiving adequate support and care, which would be contrary to signs of neglect. In summary, an unhealthy and dirty appearance distinctly highlights neglect because it indicates a failure to provide essential care that is crucial for a child's development.
