A second party sale happens when what occurs?

A second party sale occurs when someone purchases alcohol with the intent to give it to an underage person, which is the essence of option C. This type of transaction is particularly concerning as it circumvents the legal restrictions against providing alcohol to individuals who are not of legal drinking age. It highlights the responsibility of sellers to verify the age of the person they are selling to and to understand that passing alcohol to minors through another individual, rather than selling directly to them, still constitutes a violation of liquor laws.

In contrast, the other scenarios describe situations that do not fit the technical definition of a second party sale. Selling alcohol directly to minors or having an underage person attempt to make a purchase typically involves direct interaction and immediate sale, which is addressed by different legal provisions. Sharing drinks among friends may involve underage individuals but it does not reflect a sale of alcohol and therefore is not categorized as a second party sale in legal terms. Therefore, the focus on how alcohol is transferred and identifying the intent behind the sale is crucial in understanding why option C is the correct answer.
