OG10－42：关于worried的问题

42. The current administration, being worried over some foreign trade barriers being removed and our exports failing to increase as a result of deep cuts in the value of the dollar, has formed a group to study ways to sharpen our competitiveness.
(A) being worried over some foreign trade barriers being removed and our exports failing
(B) worrying over some foreign trade barriers being removed, also over the failure of our exports
(C) worried about the removal of some foreign trade barriers and the failure of our exports
(D) in that they were worried about the removal of some foreign trade barriers and also about the failure of our exports
(E) because of its worry concerning the removal of some foreign trade barriers, also concerning the failure of our exports

做此题时，我先看的worry的时态，直接就选了B，结果错了，答案时C

如果代入正确答案就是 "The current administration, worried about ..., has formed ..."我想问的问题是这个worried放在administration后，岂不是表示当局被担心，而不表示当局担心…的主动语态啊，这里该如何理解？

OG上好像没有关于这个问题的解释，只有平行结构和worry about词组的解释。

thanks a lot !!!
