Which form of abuse specifically involves non-consensual sexual acts?

The correct choice pertains to sexual abuse, which is specifically characterized by non-consensual sexual acts against an individual. This form of abuse includes a wide range of behaviors, from unwanted sexual touching to sexual assault and rape. It involves a violation of a person's autonomy and is often accompanied by a significant power imbalance between the abuser and the victim.

In the context of the question, it's important to note that sexual abuse is defined by the lack of consent, making it distinct from other forms of abuse. Emotional abuse involves manipulative behaviors that affect a person’s self-esteem or emotional well-being, neglect refers to the failure to provide necessary care or support, and physical abuse usually encompasses intentional physical harm. These forms of abuse do not involve non-consensual sexual acts, thus reinforcing the importance of understanding the specific nature of sexual abuse as a unique and serious violation.
