1.need要么接原型做情态动词,要么接to所以答案B错误
2.need的否定:need做情态动词的时候后面直接跟not;后面接不定式to的时候need是不及物动词它的否定形式应该是do not need to
所以答案应该选择第三项

needn't come 是正解,不需要做某事:needn't to do sth

选c
don't need to do = needn't do = don't have to do不必做某事

选3.此处need作为情态动词,所以need与come之间无需任何其它词

needn't come (不必做。。)
need在这是助动词故不用to,
need coming显然不对

3
need既可以作情态动词,又可以作实意动词
作情态动词,用法同may,must等词相同,后面跟动词原形,否定形式直接在need后加not
作实意动词,后面要跟不定式,也就是to do,否定形式前面加don't
所以这里可以是needn't come(情态动词)
也可以是don't need to come(实意动词)...
