选项D和选项E比较起来，差异有两点：
1、选项D用了both by concern ... and by fears ...，而选项E用了by both concern ... and fears ...。
2、选项D用了forcing伴随状语，选项E用了which forced非限制性定语从句。
我的理解是：
第1点应该没有太大差异，不太影响正误判断。
第二点中，选项D伴随状语的逻辑主语应该是主句的谓语动词，但currency本身不能force the central bank to do xxx；而which从句指代的对象应该是除against介词短语以外紧邻的名词a record low，历史最低点迫使中央银行xxxx，合理。
