In which line signals the beginning of the narrative within the frame story? when she was nine, my daughter kathleen asked if i had ever killed anyone. keep writing these war she said, i guess you killed it was a difficult moment, but i did what seemed right, which was to say, course and then to take her onto my lap and hold her for a while. he was a short, slender young man of about twenty.

"He was a short, slender young man of about twenty."

In the story this is the beginning of a new paragraph after the author states that now he writes the stories so one day his daughter will be able to know them. The other choices are about his daughter and hints at the reason for why he writes the stories. However, none of the other options are at the beginning of the narrative, they are all part of the frame story, and only about the frame story.
