Final answer:
The archetype referred to as "the central character, gives us a window into the story" is D) The Hero, who is often the protagonist representing society's moral values and offers the audience a perspective to experience the story.
Step-by-step explanation:
The character described as "the central character, gives us a window into the story" in terms of Campbell's archetypes is D) The Hero. The Hero is often the protagonist of a story, exemplified through figures like Superman. This character generally represents the moral values of the society depicted within the narrative and is someone with whom the audience is meant to identify and often look upon favorably. While any character can be an archetype, which is defined as an original model or pattern, the Hero specifically gives readers or viewers a perspective through which they can experience the story's events and character developments.
Therefore, the correct option is D.
