为什么这题要用句子，不用分词后置定语

6.    Many economists predict that the next recession, when it comes, will be caused by Federal Reserve action taken to prevent an inflationary upsurge that would result if the economy were to expand at an annual rate of three percent or more.

(A) taken to prevent an inflationary upsurge that would result

(B) they took for preventing an inflationary upsurge that would result

(C) taken to prevent an inflationary upsurge resulting

(D) they took to prevent an inflationary upsurge resulting（A）

(E) taken for preventing an inflationary upsurge that will result

答案是A，但是为什么不是c，我也觉得A很顺，可是一般可以用分词后置定语都可以优先于句子，是不是有if从句所以前面不能用动词引导？希望有一个可通用的规律或语法规则来说明。
