Correct option is B
The statement "James Ellroy started writing crime fiction, commencing with Brown's Requiem (1981) because his mother was murdered in 1958" is not correct. Ellroy has said that he was inspired to write crime fiction by a number of factors, including his mother's murder, but that it was not the sole reason.
In an interview with The Guardian, Ellroy said:
"I started writing crime fiction because I'd read a lot of it and I loved it. I also wanted to write about the Los Angeles I knew, which was a dark and violent place. My mother's murder was a part of that, but it wasn't the only thing that influenced me." Ellroy has also said that he was inspired by the work of other crime writers, such as Dashiell Hammett and Raymond Chandler. He has also said that he was drawn to the genre because it allowed him to explore themes of violence, corruption, and redemption. It is important to note that Ellroy's mother's murder was a traumatic event in his life, and it had a profound impact on him. He has said that he uses his writing to exorcise his demons and to come to terms with his mother's death. However, he has also said that he is not interested in writing about his mother's murder directly.
In conclusion, the reason that James Ellroy started writing crime fiction is not correct. He was inspired by a number of factors, including his mother's murder, but it was not the sole reason.
