Point of view is the mode of narration that the author employs to let the readers "hear" or "see" what happens in the story. There are three major types of point of view, first person, second person, and third person. First person uses the pronouns "I" or "we". Second person uses the pronoun "you". Lastly, the third person utilizes the pronouns "he", "she", "it", "they", or a name. In this case, the passage reads:
"She's a good dog, isn't she?" Doris said, hoping one of them would agree with her.
In this passage, the pronouns she and them indicate third-person point of view (C).
