Which of the following is a behavioral sign of child sexual abuse?

Age-inappropriate sexual knowledge is a significant behavioral sign of child sexual abuse because it often indicates that a child has been exposed to sexual content or experiences that are not suitable for their developmental stage. Children typically learn about sexuality gradually and within the context of education, family discussions, or through their peers. When a child demonstrates knowledge of sexual behaviors or terminology that exceeds what is typical for their age, it may suggest that they have been victimized or exposed to inappropriate sexual situations.

Frequent tantrums, desire for isolation, and overeating may occur for various reasons and are not uniquely indicative of sexual abuse. These behaviors can be responses to stress, anxiety, or other emotional issues. While they may be associated with abusive environments, they are not specific indicators of child sexual abuse by themselves. Instead, age-inappropriate sexual knowledge directly points to concerns about a child's safety and possible victimization, making it a critical sign for adults to recognize and address.
