885-sA-01,关于while后面的being的问题，以前的讨论没有涉及

Revered by an ill-informed citizenry, the Duke of York was feted opulently for several months before there was denunciation and exile.
 

(A) there was denunciation and exile
 

(B) he was to be denounced with exile
 

(C) being denounced and exiled
 

(D) denunciation and his exile（C）
 

(E) being exiled, having been denounced

找到前面的帖子说D错是因为限定词导致的不对称，但C的being作何解呢？

before being denouced and exiled难道不可以改为before denouced and exiled吗？求NN解答

难道是因为标题不够详细吸引不了人？继续坚持问……
