Answer:
a. a third-person limited narrator has insight into only one character, while a third-person omniscient narrator can see all the characters' actions and know their thoughts.
Step-by-step explanation:
The third-person narrative can be either omniscient or limited, when it is told by a third-person limited narrator, the story is told from a closed perspective, focusing on the actions, thoughts, and feelings of one character at the time (usually the main character). On the other hand, when it is told by a third-person omniscient narrator, the narrator knows all of the thoughts and feelings of all of the characters in the story and may describe any part of the story.
