 Explanation: 
 The reason for the answer comes from understanding what a point of view is, and the purpose of using it. In literature, most precisely, a point of view is the means by which an author, or it can also be a character, expresses his/her personal standpoint on a situation, an event, another person, or a topic in general. In essence, it is the way that the author puts his/her personal touch, into a story and makes himself visible through the text. In order to do this, the author uses a series of elements, basically in the narration style, that help to portray a point of view.
