[求助]难题请教 关于which的用法

Q2:

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

答案选b，可是which要就近修饰country啊，想不通。我选了E，尽管我认为E的to 10% from 6%不太符合常规

最近指代是相对信错误（新东方和牛人总结的）

是最后考虑的问题。

e是绝对性错误，必然不选！~

我认为是这样的！~

这是我的看法而已

欢迎牛人赐教
