191.For the last five years the Dutch economy has grown faster than Britain, France, or Germany, with the unemployment rate having remained well below that of the other three countries.  

A. Britain, France, or Germany, with the unemployment rate having remained

B. have those of Britain, France, or Germany, and the unemployment rate remaining

C. have Britain, France, and Germany, and the unemployment rate has remained

D. the economy of Britain, France, and Germany, with the unemployment rate that has remained

E. the economies of Britain, France, and Germany, and the unemployment rate has remained

答案是E我知道，但是我想问的是B、C两个选项为什么会有have出现在Britain，France之前~这是什么语法现象？如果说是比较结构补出助动词，可是助动词的补出不是应该在Britain之后吗？为什么在之前就补出了？求文~~
