问题如下：
Monte Carlo simulation is flexible and allow financial engineering to price complex financial instruments, Which of the following statements is not a disadvantage of the Monte Carlo technique when solving problems ?
选项：
A.High computational costs arise with complex markets and issues.
B.Results of most Monte Carlo experiments are difficult to replicate.
C.Simulation results are experiment-specific because financial problems are analyzed based on a specific data generating process and set of equations.
D.Since Monte Carlo simulations always draw random variables from a normally distributed population, they are not accurate when the input variables have fat tails.
解释：
D is correct
考点：Monte Carlo缺点
解析：蒙特卡洛模拟的输入变量或者参数不一定非要服从正态分布，可以根据实际情况进行调整，分布来满足试验的需求。其缺点主要在于使用分布和实际分布不一致会导致试验结果的偏差。
Which of the following statements is not a disadvantage。。。？这道题我理解的是问MCS的优点。看了解析说是缺点，所以没理解
