Answer: b) narrator
Explanation: Narration is merely optional in most other storytelling formats, such as films, plays, television shows, and video games, in which the story can be conveyed through other means, like dialogue between characters or visual action. The narrative mode encompasses the set of choices through which the creator of the story develops their narrator and narration: Narrative point of view, perspective, or voice: the choice of grammatical person used by the narrator to establish whether or not the narrator and the audience are participants in the story; also, this includes the scope of the information or knowledge that the narrator presents. Narrative tense: the choice of either the past or present grammatical tense to establish either the prior completion or current immediacy of the plot Narrative technique: any of the various other methods chosen to help narrate a story, such as establishing the story's setting (location in time and space), developing characters, exploring themes (main ideas or topics), structuring the plot, intentionally expressing certain details but not others, following or subverting genre norms, and using various other storytelling devices and linguistic styles
