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

请问b错在那里了，这道题我是这样分析的：the company 是单数所以看b,d ,e。

d的语序混乱排除，剩下b和e.但是不是不经常用 the country’s 这样的所有格吗？为什么选e呢？b 不对的原因是因为which ranges前面是counties,指代错误吗？如果这样是不是所有的定语从句都只修饰which 或that 之前的那一个单词？

请赐教，多谢啦
