Charlie's Angels, e.g.

TRIO

Think of a small group often seen together in music, comedy, or classic detective shows.

"Charlie's Angels, e.g." refers to the classic TV show and films featuring three female detectives working together. The phrase hints at a group of three, which is what "trio" means. Since "Charlie's Angels" is a well-known example of a three-person team, the answer is simply the word for that kind of group.
