问题如下：
Company A and company B are in the automotive industry. If the unit sales volume and operating risk of the two companies are the same, it is very likely that they have the same:
选项：
A.business risk.
B.sales risk.
C.degree of operating leverage.
解释：
C is correct.
If the unit sales volume and operating risk of the two companies are the same, we can draw the conclusion that the two companies have the same sensitivity of operating earnings to changes in the quantity of goods sold, which means they have the same degree of operating leverage. Sales risk is linked with the uncertainty of the price and quantity of goods and services. Business risk contains both sales risk and operating risk.
根据DOL的公式，如果DOL相等：
DOL = Q(P - VC)/[Q(P - VC) - FC]
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？
