What constitutes a legal supply of liquor to a minor in a private residence?

The aspect that defines a legal supply of liquor to a minor in a private residence is that it must be supplied by a legal guardian or parent who is present during the consumption. This provision recognizes the adult's role in overseeing the minor's activities and ensuring that the environment is safe and monitored. It is also designed to prevent minors from accessing alcohol unsupervised, thereby reducing potential risks associated with underage drinking.

Other options involve scenarios that do not comply with legal standards surrounding the supply of alcohol to minors. For instance, selling liquor to a minor's friends would not be considered a legal act, as it promotes access to alcohol without parental supervision. Providing liquor during a public gathering does not guarantee the presence of a legal guardian for each minor, which may lead to situations of unsupervised consumption. Finally, giving liquor to minors outside the home further removes the necessary supervision and management of the situation, making it illegal. Thus, providing alcohol in a controlled and supervised manner by a parent or guardian remains the acceptable legal framework in this context.
