请问这题答案为何是d，是谁修饰谁呢？

40.   The average weekly wage nearly doubled in the 1970’s, rising from $114 to $220, yet the average worker ended the decade with a decrease in what their pay may buy.

(B) with what was a decrease in what they were able to buy

(C) having decreased that which they could buy

(D) decreasing in purchasing power（E）

(E) with a decrease in purchasing power

请问答案e的with 是不是只能修饰主语 the average worker，with前加了逗号跟没加逗号在句子中的作用有差吗？

    d是不是因为decreasing有可能修饰decade而错
