单项选择,渴望有解释的回答
The medicine has many functions,__are unknown to us
A SOME OF WHICH
B that some of them
C of which some of them
d whcih of them
选哪个,别的为什么不行,这是关系从句吗?

a

答案A.some of which
The medicine has many functions,(some of which) are unknown to us.
翻译:药有许多功能,鞭中一些我们尚未得而知.
改写
The medicine has many functions.Some of the functions are unknown to us.
some of which引导的是一个定语从句,修饰前面的functions
其他几个无论从语法还是意思上都不合理
