What is the consequence of a final conviction for furnishing alcohol to a minor?

When someone is convicted of furnishing alcohol to a minor, one of the primary consequences involves the automatic suspension of driving privileges. In many jurisdictions, this suspension is directly tied to the nature of the offense to discourage such behavior and enhance public safety. Therefore, the correct response indicates that the individual will face an automatic suspension of their driver's license for a period of 180 days. This measure serves as both a punitive action and a deterrent aimed at preventing future violations of the law related to alcohol distribution to minors.

The other options do not accurately reflect the legal consequences mandated by law in this situation. While jail time and other specific penalties may be applicable, the automatic suspension for 180 days is a definitive and immediate consequence associated with the offense, thus making it the correct choice.
