In the adaptation, the biggest difference made was how he worded it to make it sound like it was happening in present tense.
Details were changed but not enough for it to be the main reason that the story felt like it was happening live so C. and D. are wrong.
The perspective was already in first person to begin with so A. is wrong as well.
The only option left is B. and we can see that he does change the story to be in present tense which is a good explanation as to how the story sounded like it was happening live.
Authors can exaggerate a time in history when doing fiction because it is fake, they also use vocabulary for the age gap they are writing for so the reader can best understand it based on their level of reading
