Question: When I told my father that I was moving to Des Moines , Iowa , he told me about the only time he had been there . It was in the 1930s, when he was an editor of the literary magazine of Southern Methodist University (SMU) in Dallas , Texas . He also worked as a professor at SMU , and there was a girl student in his class who suffered from a serious back disease . She couldn't afford the operation because her family was poor. Her mother ran a boarding house in Galveston , a seaside town near Houston , Texas . She was cleaning out the attic   one day when she came across an old dusty manuscript  . On its top page were the words , "By O. Henry". It was a nice story , and she sent it to her daughter at SMU , who showed it to my father . My father had never read the story before , but it sounded like O. Henry, and he knew that O. Henry had once lived in Houston . So it was possible that the famous author had gone to the beach and stayed in the Galveston Boarding house , and had written the story there and left the manuscript behind by accident. My father visited an O. Henry expert at Columbia University in New York , who authenticated the story as O. Henry's . My father then set out to sell it . Eventually , he found himself in Des Moines , meeting with Gardner Cowles , a top editor at the Des Moines Register . Cowles loved the story and bought it on the spot. My father took the money to the girl . It was just enough for her to have the operation she so desperately needed. My father never told me what the O. Henry story was about . But I doubt that it could have been better than his own story . According to the text , why did the author's father go to Des Moines ?

Choices:
A) To sell the O. Henry story.
B) To meet the author himself.
C) To talk with the O. Henry expert.
D) To give money to the girl.
