nobody作主语时,
否定词出现在句子中,反义疑问句用肯定.
nobody 做主语,附加疑问句中主语一般用he（书面语）/they（口头语）..
这句话的语境属于口语语境
故选择C.
选C
can的反意疑问句一般要分两种情况来说.
（1）can如果是表示“能力/许可/请求”等时,则直接以can来变即可.
如你的例子：He can't go to school today, can he?
例句中的can表示的就是能力的含义.
（2）can如果表示可能性”,即翻译成“可能/不可能”,则与can无关,必须考查句子的具体时态和谓语动词形式,进行具体判断.
如你的第2个例子,can就是表示可能性的含义.
例如：
1）He can't work here now,does he?
翻译：他现在不可能在这儿工作,是吗?
方法：去掉can后,结合时间状语now,则句子正常写法为：
He doesn't work here now, does he?
2) He can't have done his work last night,did he?
翻译：昨晚他不可能做过他的工作,是吗?
方法：去掉can后,结合时间状语last night,则句子正常写法为：
He didn't do his work last night, did he?
