Explanation:
The option that best summarizes the irony in the story is option D "The reader and the man from the West learn that the friend he has been waiting for, Jimmy Wells, is actually the police officer and has turned him in for crimes he committed in Chicago".
From the story, Jimmy Wells and Bob were friends and lived in New York City before their paths diverged. Jimmy stayed in New York while Bib moved to
the West but they promised that they'll meet twenty years later at a particular restaurant.
After twenty years, Bob waited at the restaurant. The irony was that a policeman then passed who asked Bob what he was doing and he explained to him but Bob didn't know that the policeman was his friend who he was waiting for which is Jimmy Wells.
Later, a plainclothed officer arrived who Bob thought was Jimmy Wells but wasn't him and he later realised that the first officer was indeed Jimmy Wells.
