问题如下图：
选项：
A. 
B. 
C. 
解释：
same unit sales volume 推出Q相同（P可能不同，未知）
same operation risk推出VC和FC相同
business risk由于P不确定，所以不一定相同，sales risk也是同理
但是C选项DOL的公式，也一样涉及到P啊？为什么就相同啦？

Business risk contains both sales risk anoperating risk. 1、是不是operating risk相同，gree of operating leverage（L）就相同？2、是不是financirisk相同，gree of financileverage（L）就相同？3、gree of operating leverage（L）既包括operating risk，又包括sales risk，是否operating risk和sales risk都相同，gree of operating leverage（L）才相同？

NO.PZ2018062005000038 根据L的公式，如果L相等 L = Q(P - VC)/[Q(P - V- F题目已知，Q相等，FC也相等。 意思就是 P-VC相等，但是推不出P相等，所以Sale risk不一样，对吗？
