Which behavior between minors requires a mandated report if one participant is older than 21?

The correct answer is that lewd and lascivious behavior requires a mandated report if one participant is older than 21, as this constitutes a potential criminal offense involving the exploitation or abuse of a minor. In many jurisdictions, any sexual activity or behavior that is deemed lewd or obscene, particularly when one participant is significantly older, places the older individual in a position of legal culpability due to the inherent power dynamics and potential for coercion or manipulation. This aligns with the responsibilities of mandated reporters, who are required by law to report any suspected child abuse or exploitation.

In contrast, consensual sexual activity between minors may not require a report if both parties are within an age range that is considered appropriate by law, often referred to as "Romeo and Juliet" laws. These laws exist to prevent the criminalization of consensual sexual relationships among minors who are close in age. In a case where one party is over 21, the nature of the relationship may be scrutinized under laws regarding statutory rape, but consensual interactions between minors generally do not invoke the same mandatory reporting duty unless there are signs of exploitation.

Thus, lewd and lascivious behavior is clearly defined and recognized as more serious from a legislative perspective, prompting
