请教一道gwd的sc TN-1-Q2

detectiveyangs

By merging its two publishing divisions, the company will increase (their share of the country's $21 billion book market from 6 percent, a market ranging) from obscure textbooks to mass-market paperbacks.
B from 6 percent to 10 percent its share of the $21 billion book market in the country, which ranges
E to 10 percent from 6 percent its share of the country's $21 billion book market, which ranges
我选择的是E，GWD答案是B。我觉得B最大的问题是which ranges貌似修饰的不是book market 而是country。而E正确使用了which ranges。而且看老外们的讨论，说to**from**这个短语也是存在的，很多人也都选择了E。
请问NN们到底哪个选项才对呢？
拜谢！

我也选的E，答案仿佛错了……

我选的B 第一次读的时候B最顺 状语 In the country  应该放在最后面 感觉重心是这样  
我是初来乍到 前两天做了第一套GWD

我拷的新版答案是E，又仔细读了下题，发现虽然E是to。。。from但不影响句子理解，且which定从修饰的应该是market，所以排除B
至于差异部分the country`s 21 billion book martket还是the 21 billlion market in the country, 感觉限定的内容有差异
