Which of the following best defines a protagonist?

The definition of a protagonist refers specifically to the central character in a narrative, around whom the plot develops and with whom the audience typically empathizes. This character is often faced with challenges or conflicts that drive the story forward and engage readers or viewers emotionally. Protagonists can exhibit a range of qualities and complexities, from being heroic to flawed, but their centrality to the story is what defines them in this role.

The other options present roles that are distinct from that of a protagonist. For instance, a character in direct opposition to the main character serves as an antagonist, which creates conflict but is not the focal point of the story. Minor characters, as referred to in another option, generally support the plot or develop the main character but do not drive the narrative in the way the protagonist does. Lastly, while settings can influence characters and plot developments, they are not characters themselves and do not fit the definition of a protagonist. Understanding the nucleus of a narrative—the protagonist—helps in analyzing story dynamics and character development.
