这道题目比较的成分是什么？

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 一开始我想的最好的结果是as varied as that of China......后来好像没有这个答案，所以说这里比较的是countries和China，the Netherlands, and Hunagary ?
B. as varied as are
C. as varied as those of
D. that are as varied as
E. that are varied as are

个人觉得不是比较结构吖~  觉得应该就是说countries有各种各样如china,the Netherlands, and Hungary^^

一开始我也是这样想的，只是看到as....as的结构，我又犹豫了，难道说这种结构可以不用做比较？
