In which sentence is the quoted word used correctly?

The word "illicit" refers to something that is unlawful or not permitted, particularly in legal contexts. In the sentence provided, saying that David was arrested for possession of "illicit" drugs appropriately uses the term to describe drugs that are illegal to possess. This reflects the correct application of the word, emphasizing the illegal nature of the substances involved, which is an important distinction when discussing law enforcement and illicit activities.

The other sentences either misuse the terms or confuse similar-sounding words. The first choice incorrectly uses "elicit," which means to draw out or bring forth, when the context calls for a term related to legality. The third and fourth choices misapply the words "council" and "counsel," which refer to a group that provides advice or the act of advising, respectively, rather than the context in which they are being used in those sentences.
