The subject of "What is interesting is that I do not even know him "is __________.A. what  B. interesting  . what is interesting D. I 请详细给出理由，谢谢！ 
回答：C.what is interesting 

我觉得题目要问的是后面这句话"What is interesting is that I do not even know him "的主语是什么

The subject of ...... 

"What is interesting is that I do not even know him "的谓语是第二个is，所以is前面的就是主语，即"What is interesting ",意思是“有意思的是我从来不知道他”。
