这一题对我比较烦，问个句子成分

ukyo2003

Laos has a land area about the same as Great Britain but only four million in population, where many are members of hill tribes ensconced in the virtually inaccessible mountain valleys of the north.

(A) about the same as Great Britain but only four million in population, where many
(B) of about the same size as Great Britain is, but in Laos there is a population of only four million, and many
(C) that is about the same size as Great Britain's land area, but in Laos with a population of only four million people, many of them
(D) comparable to the size of Great Britain, but only four million in population, and many
(E) comparable to that of Great Britain but a population of only four million people, many of whom

我做对了答案是E，但是我对E的many of whom are members of 做什么句子成分不是很清楚，这算什么成分？同位语，状语，还是什么？谢谢，语法角度分析。

这个句子的句子结构是：laos has a land area(modifier) but (has) only a population of xx people, (modifier)修饰people，其实这个题可以这么选，首先看are numbers就知道前面应该是人，那么前面的代词就应该能指代人，ABD都排除了，C选项but后面awkward，明明many of them修饰前面的people，但是变成了独立句子了

我认为many of whom 是代指说明了前面的 a population of only four million people
而作为后面从句的主语部分 我认为是非限制性定语从句 所以 many of whom 是关系代词

哦，所以many of whom是非限定定语从句，我以前以为只有, which才能引导非限定性定语从句，没想到这个也可以。
