Which of the following is considered a physical indicator of neglect?

The correct choice, which identifies unexplained lacerations or abrasions to the mouth or external genitalia as a physical indicator of neglect, highlights a significant concern regarding a child's safety and wellbeing. Neglect typically refers to a caregiver's failure to provide for a child's basic needs, which can manifest in various physical signs. In this case, lacerations or abrasions, especially when unexplained, can suggest that a child is experiencing abuse or severely inadequate care, pointing to neglectful circumstances where proper supervision and protection are lacking.

The other options describe situations indicative of a child's positive engagement and support in an educational environment. Consistent honor roll performance, regular attendance at school functions, and having a personal tutor all represent scenarios where a child is receiving adequate support, attention, and educational resources, which are contrary to the signs of neglect. They imply that the child is thriving and has involved guardians, which directly contrasts with the indicators of neglect represented in the correct answer.
