这道题的提问和各个答案请解释一下

NO.PZ2016010802000138 问题如下 Whis the most important effeof labor proctivity in a cost-push inflation scenario? A.Rising proctivity incates a strong economy ana bitowar inflation. B.The proctivity level termines the economy’s status relative to its \"naturrate of unemployment.\" C.proctivity growth proportionately excee wage increases, propriincreases are less likely. is correct.For proctivity, or output per hour, the faster thit cgrow, the further thwages crise without putting pressure on business costs per unit of output.考点cost-push inflation解析劳动生产率的提高其实是变相地降低了生产成本，不会引发成本型通胀，所以A不入选。naturrate of unemployment. 是由多种因素共同决定的，不光是劳动生产率，所以B不入选。如果工人劳动生产率超过了工资，那么商品的成本应该下降而不是上升，就不会引发成本推动型通胀，C入选。 “如果工人劳动生产率超过了工资，那么商品的成本应该下降而不是上升，就不会引发成本推动型通胀，C入选。”首先劳动生产率和工资这两个的量纲都不一样，怎么比较呢？其次为什么超过了，商品的成本应该下降呢？
