What does "the cream of the crop" refer to?

"The cream of the crop" is an idiomatic expression that signifies the highest quality or the best individuals within a particular group. This phrase originates from the process of milk production, where the cream rises to the top and is considered superior to the rest of the milk. In various contexts, whether in academics, sports, or any other field, this expression implies that it refers specifically to those who excel or stand out distinctly above others. This illustrates a clear concept of excellence, making it evident why this choice is the most accurate representation of the phrase's meaning. The other options do not align with the intended connotation of superiority and thus do not represent what the phrase conveys.
