I lost a book,___ I can't remember now.

C

I lost a book ,___I can't remeber now.

定语从句

前面的a book是先行词，在从句中做remember的宾语

一般定语从句的先行词后面都要加连系代词

表示人的先行词，在从句中做主语用who代替，做宾语用whom代替，做定语用whose代替；有时也用that来代替

表示物的先行词，在从句中用that或which代词，如果连系代词前面有介词，则一定要用which，非限制性定语从句，即连系代词不直接与先行词相连接的，也要用which

根据上面的语法知识，排除BC，因为没有连系代词，排除D，因为非限制性定语从句不能用that，所以只能选A

用whose代替its的从句很少见，我甚至是第一次见到，算是学了一点吧，这里最好还是用

the title of which

I lost a book,____ I cannot remember now.

A

只需注意一点，逗号不能起连接作用

PS。the title of which 是可以的

如果想用选项B的这类表达形式，正确的形式为：the title of which。定语从句引导词that不能作介词的宾语。
