答案是B
a) 关系代词who的用法
i.who 的前行词必须是人,在从句中可以担任主语,往往也可以代替在从句中担任宾
语的whom,但是它前边不能有介词,如果带了介词就必须用宾格的whom:
（介词+whom）
This is the teacher who teaches us mathematics.
She is the girl who (whom) I met at the party.（可以替代）
She is the girl whom (who) I went there with.（可以替代）
She is the girl with whom I went there.（不可替代）
ii.who,that在很多情况下可以通用,但是有些情况只能用who:
1.先行词是one,ones,anyone的时候宜用who.
One who has nothing to fear for oneself dares to tell the truth.
The ones who flatter me don’t please me.
Don’t tell anyone about the news who oughtn’t to know it.
Anyone who fails to finish the task given should be criticized.
2.先行词为those的时候,宜用who为关系代词
Those who were not fit for their work could not see the beautiful clothes
made of the magic cloth.
Those who want to go to the Great Wall sign up here.
3.当先行词有比较长的后置定语的时候
I met a foreigner in the street yesterday who could asked me questions in
Chinese.
4.一个句子中带有两个定语从句,其中一个定语从句的关系代词为that,另一个则用
who.
The boy that you met last night is the group leader who studies very hard.
5.在there be 开头的句子中
There is an old man who wants to see you.
There are many young men who are against him.
关系代词which的用法
在非限定性定语从句中,只宜用which,不宜用that.
Beijing,which is the capital of China,is a very beautiful city.
在限定性定语从句中which和that在指代物的时候常常可以通用,但是有时只宜用which
而不用that
i.关系代词前面有介词的时候
This is the hotel in which you will stay.
ii.如果有两个定语从句,其中的一句的关系词是that,另一句宜用which.
Let me show you the novel that I borrowed from the library which was newly
open to us.
3.关系代词与介词,关系代词的省略
a) 关系代词和介词
介词放在关系代词的前面时,介词短语只能用which代物,和用whom代人
This is the hero of whom we are proud.
I want to find the very pen with which I wrote that letter.
当介词放在句子的末尾时,可用that/which代物,that/whom/who来作为介词的宾语,
且这个做介词宾语的关系代词往往忽略
This is the hero that (who/whom/忽略) we are proud of.

这是一个非限制性定语从句，首先排除that，根据句意，用which指代前面一句的内容。

在定语从句的引导词里面，只有which 是可以指代前面这个句子的，这里which 指代he once saved two boy's lives这件事
what不能引导定语从句，可引导主语从句，宾语从句。
which引导定语从句时，只能指物
who引导定语从句时，只能指人
that引导定语从句，有几个特殊情况：
1先行词有比较级和最高级修饰时
2先行...
