C.  because they enhance reproduction or survival,but
D.  because they enhance reproduction orsurvival, but are
E.   because of enhancing reproduction orsurvival, but are
Answer: D

My Q:
请问以favored开头的插入语要怎麽翻译。
怎麽排除含due to的选项的。

谢谢。

because要优于due to。按照XDF的说法，因为because更简洁（像A，enhancement明显wordy了）。对B而言，出了用due to可以排除以外， but they are也是一个错误点。去掉两个逗号之间的成分，but后面应该是一个平行结构，they多余了。
关于favored的翻译问题，我是这样理解的：前面提到了selection,所以这里favored的意思是“被选择、受青睐”。即前面的traits并不是“因为they enhance reproduction or survival而在自然选择中获得青睐”，而只是随机的副产品（后文）。

due to只做表语，如be due to, 不做状语。
