再求一道解释

PREP语法笔记上的一题：
In Japan, a government advisory committee called for the breakup of Nippon Telephone and Telegraph Company, the largest telephone company in the world, so it would be
two local phone companies and one long-distance provider.
A.In Japan
, a government advisory committee called for the breakup of Nippon Telephone and Telegraph Company, the largest telephone company in the world, so it would be
B.The breakup of the world's largest telephone company, Nippon Telephone and Telegraph Company, was called for by a government advisory committee in Japan
, so it would be
C.A government advisory committee in Japan
called for the breakup of Nippon Telephone and Telegraph Company, the world's largest telephone company, into
D.The breakup of Nippon Telephone and Telegraph Company, the world's largest telephone company, was called for by a government advisory committee in Japan
, so it would beE.Called for by a government advisory committee, the breakup of Nippon Telephone and Telegraph Company in Japan
, the world's largest telephone company, was to be into

这题我自己选是选对了，但是想仔细研究语法笔记的解释，想要请教一个有关识别代词到底指代什么的问题。语法笔记中说A选项中so it would be 的it指代了主语a government advisory committee，因此是错误指代。。但是为什么呢？我自己理解成了指代the largest telephone company了。 在这种情况下是如何判断指示代词是指代什么的呢？？？求解释。谢谢

然后补充一道，原题是：(当然这句话是错误的)
Faulty voting equipment, confusing ballots, boter error, and problems at polling places have been cited by a new study of the 2000 United States presidential election, which estimated that they did not count 4 million to 6 million of the 100 million votes cast.

这题我同样也是做对了，但是在看语法笔记的解释时发现对于这句话的定语从句中的they是没有指代对象的。而我在看这个选项的时候却认为指代对象是voting equipment,.....这堆东西。。 请问我考虑的过程中犯了什么错误？？导致我总是分辨不清楚代词的指代对象。 谢谢

In Japan, a government advisory committee called for the breakup of Nippon Telephone and Telegraph Company, the largest telephone company in the world, so it would be two local phone companies and one long-distance provider.

it 之前出现过两个单数名词， committee 和 company, 因为committee是主语，从语法上讲，it 优先指代主语。所以产生歧义
