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.
1、是不是operating risk相同，degree of operating leverage（DOL）就相同？
2、是不是financial risk相同，degree of financial leverage（DFL）就相同？
3、degree of operating leverage（DOL）既包括operating risk，又包括sales risk，是否operating risk和sales risk都相同，degree of operating leverage（DOL）才相同？
