Idiom:
sth is not so much A as B
sth与其说是A,还不如说是B
主句中A和B分别是由that引导的表语从句。

其实这个句子结构不复杂的，就是：
According to ××, the cause ..... is so much that .... as that
在这里so much that 要和 as that 并列
D选项里面that从句不是并列的

谢谢你的分析，可是你这样分析答案就不是A 了~~

排除吧
A the cause is not so much that ... as that ...
B their being bred 所有格加上分词不敢说没有，但是很少有对的。
C it is ... the cause ... it做形式主语，后面的真实主语从句要用that提示
D their being bred 同B错
E it is ... the cause ... 同A错
试着翻译一下
