Answer:
The answer is quotation marks.
Step-by-step explanation:
What is point of view?
Point of view is the way a person or thing looks at the world around them. A story can be told in first person point of view, second person point of view, and third person point of view. First person uses words like I, me, my; second person uses words like you and yours; and third person uses words like they and them.
A, narration, is incorrect because narration is the description of what characters are doing and what events are unfolding. Ex: The Boy dashed home, constantly looking over his shoulder to make sure he wasn't being followed.
B, dialogue, is incorrect because it is the words a character speaks, not separation markers between dialogue and point of view.
C, first person point of view, is incorrect because this is simply a way of telling a story. It does not act as a divider between POV and dialogue.
D, quotation marks, is correct because they mark the start and ending of dialogue so the readers know what character is saying what dialogue. Quotation marks are also used to keep dialogue separate from the narration and point of view the story is told in. Ex: They walked down the dusty, dirt road, talking quietly to each other. Rodney says, "I can't wait for school to be over." This example shows that the story is being told in third person, but the quotation marks separate the dialogue, which is in first person.
