选D,解释说A里面出线了what和it2个主语，以及appear和was两个宾语
但是100题：

在两个从句中what的成分是不同的。
第一个句子中，what作主语。化简后为what appears。。。，是完整的主谓宾结构，不需要it。
第二个句子中，what作宾语。调整语序并化简后为 it claims what to be ，需要it作主语，指代company。

贴一段prep笔记中提到的内容，可以解释lz的第二个问题：

“有一种关系分句（即定语从句），它既是先行项的后置修饰语（即定语），同时又是另外一个分句结构的宾语（即宾语从句）”此分句结构就被嵌入在定语从句中，即嵌入式关系分句。
该书举例：In his breast-pocket he had a patch of scarlet, which i suppose was the paper cap serving as a handkerchief.
注意两点：
1）从句which was the paper cap serving as a handkerchief 首先是 patch of scarlet的定语从句。
2）从句which（patch of scarlet） was the paper cap serving as a handkerchief 也是i suppose 的宾语从句，即I suppose （that）the patch of scarlet was the paper cap serving as a handkerchief 。
综上所述，当一个定语从句同时是另一个主谓结构的宾语从句是，就可以写为嵌入式关系分句。

谢谢，但是怎么分辩what是做什么成分呀？是不是第二个unvailed后面没有宾语，所以what就是宾语，第一个动词后面又宾语，需要的是一个地点，what就做了介绍这个地点的主语？
