He must be at home, doesn't he？
参考知识点：
1）must表示“必须”时,疑问部分用mustn’t.如：
We must keep it as a secret,mustn’t we?我们必须对此保守秘密,是吧?
2）must表示“有必要”时,疑问部分用needn’t .如：
You must leave a little earlier,needn’t you?你有必要早点出发,对吗?
3）must表示“一定、肯定”等推测意义时,疑问部分一般不用情态动词,而和must后的动词相一致.如：
He must be in the classroom ten minutes ago,wasn’t he?十分钟前他肯定在教室,对不对?
He must play basketball very well,doesn’t he?他篮球肯定打得很好,是吗?
