Defying efforts by policymakers on both sides of the Atlantic at restraining it, the United States dollar, continuing its rise, reaching its highest level in six years against the German mark.

(A) at restraining it, the United States dollar, continuing its rise, reaching

(B) at restraining it, the rise of the United States dollar continued, to reach

(C) at restraining it, the United States dollar continued rising, and it reached

(D) to restrain it, the United States dollar continued its rise, reaching

(E) to restrain it, the United States dollar is continuing its rise, and to reach

答案是D。

如果把C选项改为

(C) to restrain it, the United States dollar continued rising, and it reached

那么这个C是否为正确的语法表达，如果是正确的语法表达，那么这时候C和D哪个更好？

没大搞清楚restraining it中的it 指代什么

不是一般情况下不向后指代嘛？那这里it指什么呢？

我对PREP对此题E答案的解释有疑问，因为在P1-31中，continue用的正是现在进行时态！
