Most victims of infectious mononucleosis recover after a few weeks of listlessness, but an unlucky few may suffer for years.

(A) but an unlucky few may suffer

(B) and an unlucky few have suffered

(C) that an unlucky few might suffer

(D) that a few being unlucky may suffer（A）

(E) but a few who, being unlucky, suffered

Why not E?

E的句子错误太多了

1、being    wordly

2、few已经指代了，又用了who

3、即便用who做定语being unlucky插入语。who suffered

  句子还缺了谓语。

短短7个单词，错了这么多

请问an unlucky few中的an是跟few搭配的吗？ 好像没有见过an few中间差adj 的
