有关于强调句省略问题who is making so much noise in the garden?——____ the children
——Who is making so much noise in the garden?
　　——____ the children.
　　A.There are B.They are C.That is D.It is
我知道答句是强调句 it is the children who are making so much noise的省略,但是这里为什么要看做是省略句?那问句是强调句吗?如果不是,为什么回答要用强调句呢?
还有人说it 是和 who 呼应不理解
