问题如下图：
选项：
A. 
B. 
C. 
D. 
解释：
A不一定正确吧，如果K升高的话，σ不一定比at the money高吧？求指导
B，在崩盘的时候，价格下降波动减少？
对于B的我没有看懂
我们讲义上的波动率微笑不是K和隐波的关系吗？这道题的B和是S和隐波的关系，这个和讲义上的规律还是一样的吗？已经不能用同样的结论去推导了吧？
A 里面，awthe money, 可以理解为，只要不是the money, 两边都是awthe money 么？还是说awthe money 只表示 Out of the money?

Compareto the lognormstribution, trars believe the probability of large wn movements in priis higher thlarge up movements. Increasing leverage lower equity prices suggests increasing volatility. 意说lower price是什么意思？如果是在价格较高的时候加杠杆，是否不正确了呢？
