Final answer:
Omniscient narrators have unrestricted access to the narrative, knowing all about a story's events and characters' inner thoughts and feelings.
Step-by-step explanation:
The correct answer to the question regarding omniscient narrators is that they have unrestricted access to the narrative. An omniscient narrator relates the story in third person and knows everything about the story's events, characters' thoughts, feelings, and motivations.
This perspective is essential for providing a comprehensive view of the story and is different from limited point of view narration, where the narrator may only know the thoughts and feelings of one character.
