关于it指代的问题

就我的理解，关于it的指代问题的语法解决方法只有一条规则：在从句中优先指代主句中对应位置的单数名词，如主语优先指代主语。但如果不是主从句结构怎样解决优先指代问题呢？比如下题的D.its指谁？还是说只要存在多个指代对象选项就算错？

ps.xdf的老师说it就近指代不可靠，所以我认为详解版的此解释有误：第一个it指代模糊,既可能指代paper production又可能指代use of wood,如果根据优先原则指代use of wood则不符合逻辑;

71. (28317-!-item-!-188;#058&003604)

Paper production accounts for approximately 40 percent of the world's industrial use of wood, and

the market for paper is growing faster than it is for all major wood products.

(A) the market for paper is growing faster than it is for all

(B) the market for paper is growing faster than the market for all other

(C) the market for it is growing faster than it is for all other

(D) its market is growing faster than the market for all

(E) its market is growing faster than it is for all other

望各nn解惑，谢！

答案是B吗

谢了，再问一句the market for paper is growing faster than it is for all ，it指the market for paper是吗？像这种a 介词b, it，或者a 介词b，which的结构代词指哪个呢
