In contrast to environmentalists proposals to limit emissions of certain

A. administration proposed calling for mandatory restriction of
B. administration proposed a call for mandatory restrictions, including those for
C. administration, proposing mandatory restrictions on
D. administration’s proposal was a call for mandatory restrictions, which include
E. administration’s proposal would call for mandatory restrictions on
答案是d，我选e。原因如下：
