Point of view is a critical narrative technique in storytelling, and each of the options you presented reflects different aspects of how perspective can influence a narrative. However, if we have to choose the one that most accurately describes how point of view is used as a technique, the best option would be:
C. Allows the writer to tell what every character is thinking.
This choice refers to the use of third-person omniscient point of view, where the narrator has access to the thoughts and feelings of multiple characters, providing a broader understanding of the story and its dynamics. Other perspectives like first-person or third-person limited would focus more on individual characters' experiences, but option C encapsulates one of the most powerful uses of point of view in narrative technique.
