Your supervisor is an expert in market and credit risk. He recruits you to manage the operational risk department. He would like to use VaR to measure the firm's operational risk and proposes that you use the same VaR framework previously developed for market and credit risk. Which of the following is a valid argument for why it is difficult to estimate an operational VaR using the same framework as market and credit VaR? A.Market risk events are easier to map to risk factors than operational risk events. C.Market and credit VaRs are estimated using only frequency distribution, but operational VaR is estimated using both a freq distribution and a severity distribution. 其他B,D肯定错，但是不明白为什么C错和A对，为什么market risk更容易map to risk factors? 请老师解答一下，谢谢！
