_ Tom _to work hard to help his family ?

Yes, he _.

A. Has… x…does B. Has…x…does

C. Does…has…has D. Does… have…does

汤姆需要努力工作来帮助他的家人吗？

解析：
D：
前面有does ,疑问句中do后紧跟着的词要用原型。

do的疑问句后接的为何是原型：
比如She likes running in the early morning. 改成一般疑问句那就是Does she like running in the early morning?
这里的like就应该用动词原型了，而不是动词的第三人称单数形式。
