A:Bad luck.They didn't offer the job to me.B:_____you've been well prepared for the interview.
A.So what?
B.What it?
C.How come?
D.what about?
答
C
根据后半句：you've been well prepared for the interview.这里的interview当然是job interview,所以推测出这个对话发生在工作面试之后.A说没拿下工作,B的自然反应会是：怎么会?=〉How come （that they didn't offer you the job省略）?
