Which of the following actions is included under "Sexual abuse"?

The correct answer focuses on specific sexual offenses that fall under the definition of sexual abuse, particularly in the context of child protection laws. Actions such as incest, rape, or sodomy involve sexual acts that are not only criminal but also inherently exploitative and harmful, especially when involving minors. This classification underscores the serious nature of these acts and their profound impact on victims, making them core components of what "sexual abuse" encompasses legally.

In terms of context, emotional manipulation, child abandonment, and failure to provide education, while potentially harmful and often related to neglect or emotional distress, do not necessarily involve sexual exploitation or abuse. Therefore, they do not fit within the legal framework that defines sexual abuse, which is specifically aimed at identifying acts that sexually violate an individual, particularly when that individual is a vulnerable child.
