Which two groups are classified as "prohibited persons"?

The classification of "prohibited persons" primarily includes individuals who are legally restricted from entering licensed premises where alcohol is served. Minors, defined as individuals under the legal drinking age, are prohibited from entering these venues to prevent underage drinking and promote responsible consumption of alcohol. Intoxicated people are also considered prohibited persons because allowing them entry could lead to irresponsible behavior and potential harm to themselves and others, contravening the principles of responsible service of alcohol.

In contrast, the other groups mentioned in the options, such as employees and family members, are often permitted in licensed establishments under certain conditions, especially if they are of legal age. Visitors and volunteers may also not be classified as prohibited persons if they are of legal age and not intoxicated. Ordinary citizens, while they can include minors, can also be of legal age and therefore are not collectively classified as prohibited persons.
