答案是B  求解释~~~

namely 不是连词不能连接一个句子，所以应该namely that +句子，排除AE

C选项，it指代不明，而且句中没有任何名词能代替it。
D选项 considerable 一般是修饰抽象名词的，比如 time， money， attention, 所以 a considerable variation i不恰当;some fraternal twins resembling each other greatly and others looking quite dissimilar 在原文意思就是指fact，用 with结构+it is a fact that 是不准确的而且繁琐的：感觉with。。。。伴随的一个fact, 但其实with后面的话就是fact。
不知道你明白我的解释没？

mark一下。it is the fact that ＋陈述事实。D把要陈述的事实变成了With伴随成分，逻辑重心转移。看原句The fact of some fraternal twins resembling each other greatly and others looking quite dissimilar highlights。。。。。。主语逻辑重心在所描述的事实上。D把主语变成伴随状语了。改句子首先要尊重原句意思。OG里说的。

mark一下
1 namely不是连词
2 that引导的名词从句，受教了

补充一点：the fact of 的句式在gmat中压根就没正确过，全部粗线在错误的选项
