Explanation:
Hi. Although you have not introduced the book this question refers to, we can see from the context of the question and the answer options that you are referring to the book "Frankenstein."
"Frankenstein" was written by Mary Shelley and tells the story of how Victor Frankenstein, a scientist fascinated by the possibility of creating life, manages to create a living being and suffers several consequences for this creation. Victor had been interested in science since his adolescence, but that interest was so great that it left Victor completely obsessed with the possibilities that science offered. He began studying non-stop, cutting off contact with family and friends. His goal was to fully focus on the study of science and the possibility of creating a living being, specifically, a human being.
 
        
             
        
        
        
Answer:
4) The narrative will change depending on the narrator's tone and point-of-view.
Explanation:
It is the <em>narrator's role </em>to tell the readers/audiences about what's happening in the story. He/She becomes the<em><u> readers' lens, </u></em>thus, their knowledge will largely rely on what is being narrated. 
It is important to carefully pick a narrator when planning to write a narrative. A story can take a first-person perspective wherein the reader will have a deep connection with the main character in the story. However, his point-of-view will only be limited to what that character thinks. It can take the second-person perspective wherein<u><em> the writer or author wants to directly convey his message to the reader.</em></u> Another perspective is the third-person wherein the reader will know everything that is happening in the story. A change in perspective changes the tone of the narrator, as well as his point-of-view. This largely affects the readers'/audiences' understanding.
