I am very pleased with what you have given and___you have told me

就像中文一样，
你问别人是告诉你什么呢还是说告诉你哪个呢？
所以选择的是what
其实这句话也可以简单一点，
I am very pleased with what you have given me and told me.

这里应该填what或者all that（相当于what），所以只能选A。

因为这里即缺少WITH后面跟的 又缺少told后跟的词语 所有这里填的词语要担任双重成分，可以用what 或者all that

all that which一般来说是 which one 哪个? wihch 后面的一般都是名词和不是you i he she 等. 不能是哪个你,哪个他什么的.

答案永远是正确的

___you have told me

名词性从句不用what
