I am sure that_you said is wrong.
A all B.what
为什么不能选A

I am sure that_you said is wrong.A all B.what为什么不能选A
I'm sure (what ) you said (is) wrong.
I'm sure (all) you have done (are) wrong.
I'm sure (something) you try to hide (is) wrong

all that=what

I am sure that what you said is wrong.
A all B.what
what you said 是主语从句,表示单数

what = all that
I am sure that what you said is wrong.
I am sure that all that you said is wrong.
两句意思相同,第二句中的第一个that可以省略。

all that=what;而且that在从句中做主语,不能省略。若选A应是all that.
