Which of the following is an example of a physical indicator of serious child abuse?

Multiple bruises serve as a significant physical indicator of serious child abuse because they can indicate that a child has experienced repeated or severe physical harm. Unlike the other choices, which reflect positive aspects of a child’s life and well-being, the presence of multiple bruises typically suggests that the child may be facing neglect or violence in their environment. This situation raises concerns and necessitates further investigation by the appropriate authorities to ensure the child's safety and well-being.

Frequent school attendance, positive relationships, and high participation in sports are markers of a child who is likely in a supportive and healthy environment, making them less indicative of abuse. In contrast, multiple bruises stand out as a clear red flag that requires immediate attention and action.
