由GWD TN-1 一道语法题想到的

By merging its two publishing divisions, the company will increase their share of the country’s $21 billion book market from 6 percent to 10 percent, a market ranging from obscure textbooks to mass-market paperbacks.

1. their share of the country’s $21 billion book market from 6 percent to 10 percent, a market ranging
           
2. from 6 percent to 10 percent its share of the $21 billion book market in the country, which ranges
           
3. to 10 percent from 6 percent in their share of the $21 billion book market in the country, a market ranging
           
4. in its share, from 6 percent to 10 percent, of the $21 billion book market in the country, which ranges
           
5. to 10 percent from 6 percent its share of the country’s $21 billion book market, which ranges

b的which ranges不好
e的he country’s $21 billion book market不好

两个错误孰轻孰重，还望大家讨论！！

感觉应该是B好一些,which未必修饰前面最后一个名词,只要根据句意能推断出which指代哪个就行.这种情况在GMAT语法中出现过多次

E,感觉the country's还能说得过去,但from...to...应该不可以颠倒吧?
