求助一道语法题目！有关比较倍数的！

alanzheng1991

A recent review of pay scales indicates （that CEO's now earn an average of 419 times more pay than blue-collar workers, compared to a ratio of 42 times） in 1980.

(A) that CEO's now earn an average of 419 times more pay than blue-collar workers, compared to a ratio of 42 times
(B) that, on average, CEO's now earn 419 times the pay of blue-collar workers, a ratio that compares to 42 times
(●) that, on average, CEO's now earn 419 times the pay of blue-collar workers, as compared to 42 times their pay, the ratio
(D) CEO's who now earn on average 419 times more pay than blue-collar workers, as compared to 42 times their pay, the ratio
(E) CEO's now earning an average of 419 times the pay of blue-collar workers, compared to the ratio of 42 times

以下是答案上给出的解释：
(A) compared to的比较对象不对象，前者419 times the pay of blue-collar workers表达的是工资数， 而后者a ratio of是比率。
(B) a ratio that compares的compare不能用主动方式表达，应该是被比较sth be compared to…的省 略形式（省略了主语和系动词，是惯用法）；compare to的比较对象不对象，前者419 times the pay of blue-collar workers表达的是工资数，而后者42 times是比率。
(C) 正确，as compared to比较结构，419 times the pay与42 times their pay比较，the ratio…是同位 语。
(D) 缺少that引导宾语从句；indicates CEO's who…句子结构不完整，缺少谓语，who引导定语从句 修饰名词CEO's。
(E) 缺少that引导宾语从句；indicates CEO's earning…句子结构不完整，缺少谓语；compare to的 比较对象不对象，前者419 times the pay of blue-collar workers表达的是工资数，而后者42 times是 比率。

我觉得答案中BCE的意思是419倍，而原文中的意思是420倍，所以我首先就把这三个选项排除了。。。然后在AD总我认为A更好。。。。
求解释啊。。。
