都对的.英语中形容词有这种构词法,通过不同的方法,就构成了所谓的复合形容词.形容词是放在名词前修饰名词的,所以要么he is an eight-year-old boy,要么the boy is eight years old.这题选b.
另外,这种构词法规定,复合形容词你的名词不允许有复数.years改为year.所以C不对.
FYI：复合形容词构成方法
名词+形容词 e.g.duty-free goods 免税的货物
名词+名词+ed e.g.lion-hearted man 勇敢的人
名词+现在分词 e.g.time-consuming 耗费时间的
名词+过去分词 e.g.hand-made 手工制作的
形容词+名词 e.g.second-hand 二手的
.等等
