"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

答案是C，OG解释是 absorbing 需要和后面的protecting 平行。但是absorbing放在这里不会导致说不清先行词的是buffer还是a breakwater of rocks吗 ？

LZ看到后面的and protecting 了吗，这里absorbing与之平行
