A.did yu realize B.that you realized C.did you not realize D.that you did not realize
此题选哪个答案？

A.That
有so,就是有了他说的内容了,所以排除what
用when的话,后面就缺主语了
这是一个从句,不会空着不填
综上所述,选A.That

这里选A.....
没有so，选What...
如果when, 后面要改。。
When he said so at the meeting, he made everyone present surprised.

A that引导的主语从句
what因为已经有宾语so了所以不能选
