B.while it then proved unable to handle the increase in business and fell months behind in its payment to

C.but then it proved unable to handle the increase in business, falling months behind in its paying

D.but then proving unable to handle the increase in business, falling months behind in paying

E.but then proved unable to handle the increase in business, falling months behind in paying

这道题我做的时候就犹豫A和E~能帮忙解释下为什么A错么？我觉得its指代没什么问题~前面一个it是形式主语，后面的its就只能指代company了吧~

while 应该算是让步转折吧（虽然，尽管等），但这句话应该用强转折but
its的指代没问题，但一般情况下，如有选择，GMAT prefer 用动词 （简洁，明了）
