大全 Section A 1 没人问过

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

为啥选C啊,GMAT语法中一般出现being不都是错的吗?

望指教~谢谢!

before引导的时间状语从句，固定搭配形势：before + 句子；before +短语；before+ doing sth.
