What characteristic is typical of a stock character in literature?

A stock character is a recognizable and stereotypical character type that appears frequently across various works of literature and genres. This characteristic allows readers to instantly understand the role the character is likely to play in the story without extensive background or development. Stock characters often embody traits that are immediately familiar, such as the "dumb jock," the "wise mentor," or the "lovable rogue." Their repeated appearances across different narratives highlight their archetypal significance in storytelling, serving as a useful shorthand for readers.

In contrast, other options suggest characteristics that do not align with the definition of a stock character. For instance, stock characters are generally not known for their complexity or significant character development; instead, their predictability is often key to their function in a narrative. Additionally, stock characters do not typically hold unique traits, nor are they primarily depicted as protagonists, as they can serve various supporting roles within the plot.
