Answer:
A
Step-by-step explanation:
First person means that the story is narrated with the pronouns "I", "my", "me", etc. However, there is no part of the narration that is like this, so eliminate C and D.
Second person means the story is narrated with the pronoun "you", but again, there's no part of the narration that is like this, so eliminate B.
Third person means that the story is narrated through the thoughts and actions of a character without using "I". Instead, it uses pronouns like "he" or "she". Here, the narration is in third person through Margie's thoughts.
Hope this helps!
