Define "sexual assault."

The definition of "sexual assault" encompasses any unwanted sexual contact or behavior that occurs without the consent of the victim. This includes a wide range of actions, from inappropriate touching to more severe offenses. The key aspect of this definition is the absence of consent; without explicit and informed agreement, any sexual interaction can be deemed assault. This highlights the importance of consent in all sexual situations—the lack of it transforms an action into an act of violation rather than a consensual encounter.

The other choices fail to accurately capture the essence of what sexual assault entails. Consensual relationships imply mutual agreement and desire, which completely contradicts the concept of assault. Romantic advances and inappropriate jokes do not involve the physical and non-consensual nature of sexual assault, focusing instead on interpersonal interactions that, while they may be unwanted or inappropriate, do not fall under the legal and social understanding of sexual violence.
