问一道prep上的语法~~我苦苦追寻啊

So-called green taxes, which exact a price for the use of polluting or nonrenewable fuels, are
having a positive effect on the environment and natural resource base of countries as varied as
China, the Netherlands, and Hungary.

(A) as varied as
(B) as varied as are
(C) as varied as those of
(D) that are as varied as
(E) that are varied as are

总体来说我就是没太看明白~~它说conutries as varied as china, 就只有china么？那还countries？

luyiqing

as varied as 这个词组后面是用来解释说明前面的，这里China...等是用来解释countries的
