Which of the following categories of offences involves selling alcohol without a license?

The category of offences that involves selling alcohol without a license is unlicensed persons and unlicensed premises. This designation specifically addresses the legality of alcohol sales, highlighting that individuals or establishments must possess the appropriate licensing to distribute alcoholic beverages. Operating without such a license poses serious legal implications, as it undermines the regulatory framework designed to ensure responsible alcohol distribution, health, and safety standards.

In contrast, other categories such as irresponsible promotion of alcohol, banned and restricted alcohol, and offences relating to minors touch upon different aspects of alcohol regulation, such as marketing practices, specific product restrictions, and regulations regarding underage consumption. However, they do not directly address the violation associated with the lack of a required license for selling alcohol, which makes unlicensed persons and unlicensed premises the accurate choice in this context.
