Answer:
The difference between point of view and choice of person in a story is that “point of view” refers to the perspective from which the story is told; “person” is part of a term used to describe a type of narrator (as in first-person or third-person)
Using points of view means that an author chooses one or several characters' perspectives to narrate the events of the story from their own experiences, observations and opinions.
On the other hand, the choice of person is the one that the author uses to narrate the story: first-person, "I or "we"; second-person, "you"; or third-person, "he", "she" or "it").
For instance, George R.R. Martin's A Song of Ice and Fire has several points of view and all of his characters' storylines are narrated in third-person.
