Indecent exposure requires which of the following to occur?

Indecent exposure is a criminal offense that specifically requires the intentional exposure of one's genitals or breasts to others in a manner that is likely to cause alarm or offense. This means that the act must be deliberate rather than accidental, highlighting the importance of intent in this crime. The requirement of intentionality is crucial as it differentiates this offense from other forms of exposure that may not be regarded as indecent, such as accidental nudity.

In the context of the other options, showing oneself at a private gathering does not meet the criteria for indecent exposure since it typically requires exposure in a public place, where others can easily see. Receiving consent from onlookers also negates the notion of indecency, as consent would imply that the act is acceptable to those present; indecent exposure is supposed to cause offense or alarm. Lastly, a formal complaint from a victim is not a requirement for the crime to occur; the offense can be recognized regardless of whether a complaint has been made.

Thus, the correct answer emphasizes the necessary component of intentionality and the specific act of exposing oneself that constitutes indecent exposure.
