【求助】GWD-TN-24 Q8 PP70 关于less与costs搭配

wenchang

Employment costs rose 2.8 percent in the 12 months that ended in September, slightly less than they did in the year that ended in the previous quarter. A.less than they did
B.less than it did
C.less than they were
D.lower than
E.lower than they were

答案是A对答案没有异议，B中的it指代不清，C中的were应该是did，DE的比较级不应该用lower，但这里有个问题就是costs的比较级应该是less还是fewer？我觉得costs应该是可数名词吧？less用在这里合适么？希望NN指教

I guess it's comparing the "percent" not the "costs"

那就是说A选项是个省略，原句应该是less than the percentage they rose，是么？
