I choose D.
my points:
1. comparison:
   a. resemblance V.S. dog
   b. resemblance V.S. dog
   e. resemblance V.S. dog
2. them/their: ( not clear )
   c. them: may mean "wolves" or "researchers"

其实我是觉得这里面的选项都不太对
代词不是应该优先指代句子主语吗？
所以五个选项的动词都有修饰researchers的嫌疑吧...

我还是觉得E比C好，up一下

Choice E changes the meaning. With "for" it sounds as though we are using some kind of techniques on genetically enhanced plants; but not necessarily the techniques that caused those genetic enhancements in the first place. That is, it sounds like this: "by using techniques for [this type of plant]".

C.Employing the same techniques （used to genetically enhance plants ）so that they are

D.Employing the same techniques to genetically enhance plants, which makes them修饰前面的plants错，是技术使得植物免虫害

E.Employing the same techniques for genetically enhancing plants that make them表目的不如不定式，且that修饰plants不合逻辑
开始也错选了D，仔细看，C中used to genetically enhance plants 是修饰 techniques 的定语成分，所以后面的they指代不会有歧义

小羽羽

晕，仍然觉得C的so that 有问题，they会不会指代歧义呢?

they 指代不会有歧义， 能再深入解释一下吗？

C.Employing the same techniques （used to genetically enhance plants ）so that they are
难道没人觉得Employ和used to 有意思上redundant 的嫌疑吗？

不会重复的~这里的used是修饰前面的techniques

used这里是过去常常的意思。E选项把used省略导致句子没有了对比：the same现在用的和过去的。
