正确答案是B,that.

分析:这个一个强调句,it is .that(who)句型的考查.

选which 是因为以为这个一个定语从句,以为which引导的是修饰bedroom的定语,但其实不是.如果是定语的话,应该是这样:she was sleeping in her bedroom which a thief broke into ,后面就没有the house 啦!the house 和 bedroom重复了

这个句子的原型是:a thief broke into the house while she was sleeping in her bedroom (把 it is ..that 去掉,剩下的仍然是一个完整的句子)

,为了强调小偷进去的时间,所以把while she was sleeping in her bedroom 放在it is 和that 的中间.
