Answer: B. It gives O. Henry a way to keep key information about both main characters hidden until the end.
"After Twenty Years" is a short story by O. Henry. It was first published in his anthology <em>The Four Million</em> in 1906.
It tells the story of two friends who due to their separate paths in life have not seen each other in twenty years. However, they have agreed to meet on a particular spot near a restaurant that night. The story has a plot twist near the end, which relies on the author keeping information about the main characters hidden until the end. He does so by means of a third-person narrative.
