A needs discussing
B needs to be discussed
C needn't being discussed
D doesn't need discussing
needn't后面不是只能加动词原形吗?
答
need[英] [ni:d] [美] [nid] (及物动词）vt.需要；必须（情态动词）aux.必须；不得不；（名词）n.需要；需要的东西；责任；贫穷；（不及物动词）vi.（表示应该或不得不做）有必要；在这里的need做为动词用,所以后面...need作为动词用后面也不该用动名词形式吧need作情态动词时，后面直接跟动词原形，即need do sth.need作实意动词时，是及物动词，后面可以跟名词或者动词不定式。
