What distinguishes nonforcible sexual assault?

Nonforcible sexual assault is primarily characterized by a lack of consent rather than the presence of physical restraint or force. The correct answer highlights that if the victim is under the age of consent, they cannot legally give consent, which qualifies the act as a nonforcible sexual assault. The law recognizes that individuals below a certain age do not possess the legal capacity to provide consent for sexual activities, making any sexual contact with them nonconsensual.

In contexts involving other options, while physical restraint is associated with forcible sexual assault, it does not apply in this case. Videotaping an act is not a defining factor of whether the act is forcible or nonforcible. Additionally, the mention of the victim being aware and consenting contradicts the nature of sexual assault, as true consent must always be clear, voluntary, and informed.
