　　B.      II and IV only
　　C.      I and III only
　　D.      IV only
　　解析：
　　Answer: C
　　Explanation: The rogue traders for both Daiwa and Barings had dual roles as both the head of trading and the head of the back-office support function. This operational risk oversight allowed them to hide millions in losses from senior management. In the Allied Irish Bank case, John Rusnak did not run the back-office operations. The Drysdale Securities case did not deal with a rogue trader.
