The narrator experienced this event in person.
Answer: Option A.
Step-by-step explanation:
A first-person narrative is a mode of storytelling in which a narrator relays events in the story or the lesson from their own point of view using the first person i.e. "I" or "we", etc.
The first person point of view has been written by the author or the narrator of the story because the event that has been talked about in this particular event in the story was experienced by the author himself. So he could narrate it better with all the details in it.
