Recently implemented "Shift-work equations" based on studies of the human sleep cycle have reduced sickness, sleeping on the job, (fatigue among shift workers, and have raised) production efficiency in various industries.
括号中是划线部分

A) Fatigue among shift workers, and have raised
b) Fatigue among shift workers, and raised
C) and fatigue among shift workers while raising

为什么选C，不选A ？

3项并列的东西最后一项前面要加and，比如a,b,and c
把and加到后面变成"have raised"和 sickness等平行，就不对了
