In a plan to stop the erosion of East Coast beaches, the Army Corps of Engineers proposed building parallel to shore a breakwater of rocks that would rise six feet above the waterline and act as a buffer, so that it absorbs the energy of crashing waves and protecting the beaches.
(A) act as a buffer, so that it absorbs
(B) act like a buffer so as to absorb
(C) act as a buffer, absorbing
(D) acting as a buffer, absorbing
(E) acting like a buffer, absorb


Ron在讲解“comma+ving“ 时说道必须满足一下两条之一
* immediate consequence
* simultaneous, butlower-priority, action
但在这里，我不是很理解absorbing....protecting是属于哪一条，感觉都不太对。求NN解释！！

分词作后置定语的条件是1.主句主语一致2.解释的是句子；除此之外分词作结果状语一定是要前面句子的结果不是单单修饰主语，做伴随状语的时候一定要跟之前说的事情同时发生。
这里我个人觉得作结果状语更贴切。
