each和annually重复，D的save in employee illness prevention有歧义，感觉像是在做prevention的过程中节约了多少钱，但其实是说的通过prevention节省了一笔钱。

preventing illness在这里认为是 noun form；后面 improved worker performance也是noun form，是平行的

不要看到后面的修饰不一样就被迷惑了。

1)annually和each year重复，排除adc 2)save $ in X，X只能是banks

by preventing语义是通过防止疾病公司可以节省580亿元。较C语义更加合理。

by一个措施&through一个措施。

认为这是典型的正确选项也不是完美的例子：1. by preventing vs through improved，平行的不够工整，2. if they simply provided……代词they离先行词companies太远，中间还出现了employees这个复数名词，指代可疑。但是，annually和each year是个明显的错误，ABC肯定错，而D的平行有问题。相对而言：1. by preventing 和through improved虽然没那么工整，但都是“介词+动词分词”的形式。所以优于D。

improved working performance 是名词，improved形容词修饰用的。。。。

句意！gain billiong是通过improved worker performance，已经提高了performance worker，worker，而不是不是通过提高（improving）workers.
