What does the term "illicit" refer to in general?

The term "illicit" specifically refers to activities or actions that are forbidden by laws, rules, or customs. It indicates something that is not allowed or is considered improper within a particular legal or societal framework. Understanding this term is essential in event planning, as it underscores the importance of adhering to legal regulations and ethical standards when organizing events. Activities deemed illicit could lead to legal actions, penalties, or damage to an organization’s reputation.

In contrast, the other choices highlight concepts that align with legality or acceptance in society, which do not capture the essence of what "illicit" conveys. The correct answer reinforces the concept of legality versus illegality, which is crucial in many fields, including event planning.
