OG不是说that从句不能做主语吗?为什么这里选B?

怎么没人回答呀？？？？版主呢？？

这个是主语从句

OG里面的那道题目我依稀记得, 好像没有说不能用主语从句,只是在那道题目里面比较awkward, 但是这道不同呀.

MM 有别的疑问再讨论

A.
The fact of some fraternal twins resembling each other greatly and others looking quite dissimilar highlights an interesting and often overlooked feature of fraternal-twin pairs, namely they vary considerably

看这个主语复杂的，the fact后边跟那么多表示动作的词的时候，用从句表达更清楚。前边一个句子the fact highlightes feature,后边又加一个句子namely they vary,两个句子没有连接词，句子结构错。namely是副词不是连词

WHY???
