A character foil is defined as a character that possesses traits that are in stark contrast to those of the protagonist, effectively highlighting the characteristics and qualities of the main character. This contrast serves to emphasize particular aspects of the protagonist's personality, motivations, or values. For example, if the protagonist is characterized by bravery, a character foil might display cowardice, which sheds light on the protagonist's courageous actions. By presenting opposing traits, the foil enhances the audience's understanding of the protagonist, making their journey and choices more pronounced.

The other options describe different roles or characteristics that do not capture the essence of a foil. A character sharing similar traits would not serve to accentuate the protagonist's qualities. Similarly, a supportive character does not necessarily create contrast, and a character deemed non-essential lacks the defining role in comparison to the protagonist. Therefore, a character foil's distinguishing feature lies in its ability to provide a sharp contrast, illuminating the protagonist's unique traits.
