白勇语法第四章语法第34练习题，高手帮助

34. Japan received  huge sums of capital from the United States after the Second World War,using it to help build  a modern industrial system.

b.Japan received huge sums of capital from the United States after the Second World War and used it to help in building.

c.Japan used the huge sums of capital it recieved from the United States after the Second World War to help build

答案选ｃ，而我ｂ为什么不正确．它的解释是it 语法上应该指代主句中的单数名词the United States,但逻辑意思上应该指代复数名词huge sums of capital,代词指代在语法和逻辑上产生矛盾，错．

我觉得不太认可这个解释

因为b项it指代huge sums of capital也是比较明显的．

哪位高手能拿出更加信服的解释呢？

在此谢过
