Answer:
A). To tell the story from many different perspectives.
Explanation:
Third-person narration is demonstrated as the point-of-view in which the narrator is an impersonal observer who relates the story to the readers using the third-person pronouns like 'he, she, they, etc.' that allows him/her to offer an objective view to the audience.
As per the question, the author primarily employs third-person narrator to 'tell the story from different perspectives' as the narrator is omniscient and knows about the situation and feelings of the characters. Thus, the narrator is able to move freely across time and proffer a blend of his opinions as well as the thoughts going in the mind of the characters. Therefore, it offers an objective view to the readers through which they can read, analyze, or interpret the text independently. Hence, option A is the correct answer.
